张明聚，谢治天 （北京工业大学）
摘 要：在基坑工程内撑式围护结构中，钢管内支撑由多段法兰连接的钢管和活络端组成。 活络端是钢管内支撑体系中的重要节点之一，但是该节点能否满足“强节点，弱构件”的设 计要求目前不得而知。本文通过理论计算得到了 18m、20m、24m 跨钢管支撑的屈服荷载、极 限承载力和刚度。同时，在北京地铁工地抽取了 3 组活络端作为试件，进行了室内加载试验， 得到了各试件的荷载-位移曲线。通过比较活络端试验结果与不同跨度钢管支撑的屈服荷载、 极限承载力和刚度，得到如下结论：（1）各试件屈服荷载和刚度有很大差别，屈服荷载最大 为 4790kN，最小为 1780kN，刚度最大约为 428kN/mm，最小仅为 266.7kN/mm；；（2）双厢式 活络端的质量为单厢式活络端的一半，但其屈服荷载为 2750kN 是第二组单厢式活络端屈服 荷载的 1.6 倍，刚度为 345.7kN/mm 是第一组单厢式活络端刚度的 1.3 倍。综合比较，双厢 式活络端的性能更优；（3）强度较好的试件但刚度不足，刚度较好试件的但强度不足。所以 活络端是整个钢管支撑体系中变形的主要来源或承载能力方面的薄弱节点。

Influences of Active Node on Overall Bearing Capacity of Steel Bracing in Excavations
Zhang Ming Ju，Xie Zhi Tian （北京工业大学）
Abstract： In bracing structure in excavations, steel pipe internal support consists of steel pipes and active node connected by multiple segment flanges. The active node is one of the important nodes in the steel bracing system. However, it is not known whether the node can meet the demands of the practical engineering designs of "strong node and weak component". In this paper, the yield load, ultimate bearing capacity and stiffness of 18m, 20m and 24m steel pipe support are obtained by calculation. Meanwhile, three groups of active nodes were taken as specimens from the Beijing subway site, and the loading tests were carried out in the laboratory, and the load-displacement curves of the specimens were obtained. The following conclusions are obtained by comparing the yield load, the ultimate bearing capacity and the stiffness of the active node and the steel pipe support. (1) There is a great difference between the yield load and the stiffness of the specimens. Among the specimens, the maximum yield load is 4790kN but the minimum one is 1780kN; and the maximum stiffness is about 428kN/mm but the minimum on its only 266.7kN/mm. (2) The 6 quality of the double-box active node is only half of the single-box active node, but its yield load is 2750kN, which is 1.6 times the yield load of the second group of single-box active node, and the stiffness is 345.7kN/mm, which is 1.3 times of the first group of single-box active node. Considering the influence of bearing capacity, stiffness and economic benefit, the double-box active node is better. (3) For the active nodes, the strength is better, but the stiffness is insufficient, and the stiffness is better, but the strength is insufficient. So the active node is the main source of deformation or the weak node in the bearing capacity of the whole steel pipe support system. keywords: excavation engineering; steel strut; active node; bearing capacity; stiffne; 作者简介：张明聚，北京工业大学，电话：13910519663，邮箱：[email protected]

Abstract：Composite foundation is often utilized to reduce the post-construction settlement of high speed railway embankments constructed on the soft soil. Due to the uncertainties in the properties of the soft soil and mixed columns, the settlement of the composite foundation is also uncertain. To consider the influence of the spatial variability on the settlement, the finite difference method is used to predict the settlement of an embankment supported by the DM columns. Both spatial variability and complex interaction between soil and columns can be considered by the random field finite difference method. Sensitive analysis is conducted to the random variables investigated in this study. Effect of the spatial variability on the settlement happened during the construction period is studied, and the effect of the spatial variability on the maximum post-construction settlement is also investigated.

Abstract：The effect on the vibration of ground building caused by subway are various and comprehensive. The method of combining the theory of vehicle-track coupling dynamics with the finite element method is used to develop a finite element model of subway vehicle-track-tunnel-soil-building coupling system. Taking Lanzhou Subway Line 1 for example, three evaluation criteria of acceleration in the time domain, 1/3 octave frequency acceleration vibration level and VLZ (Vibration Level Z) are used to study the effects of buried depth and avoidance distance to the ground building vibration. The results show that the vibration responses of ground buildings caused by metro trains in the loess area are different from the vibration responses caused by the subway trains already operated in Beijing, Shanghai and Nanchang, but the overall trend of change is consistent. The change of vibration of ground buildings caused by subway ’ s operation with the change of buried depth, the vibration response of buildings is piecewise linear. When the depth is in the range of 11 ~ 19m and 19 ~ 27m, the average buried depth increases by 1m, and the maximum of VLZ decreases by 0.7dB and 1.16dB respectively. With the increase of avoidance distance of ground buildings, the general trend of vibration of ground buildings decreases gradually, but there is an amplification area of vibration at the avoidance distance around 30m.

Study on Seamless Transfer of Regional Rail Transit
Zhao Yang
Abstract： There are some shortcomings in the rail transit network, such as long -distance transfer, unreasonable transfer and so on. To solve those problems, the synchronous transfer model in the traffic network is constructed. On the one hand, based on the departure frequency and time interval of each route, the model is to maximize the number of vehicles arriving at the same time. On the other hand, the model should consider passengers’ travel time and adjust the departure time of different route trips. In the end, we can get an unevenly adjusted departure schedule. In order to verify the validity of the model, an empirical study was carried out on Dalian north station and metro station. We use the collected data to analysis and build model, and get results through programming and simulation. The results show that the model not only optimizes the departure time of the line in the network, but also reduces the transmission time and improves the transmission efficiency. Eventually formulate a new departure timetable. The model is effective to release the crowded traffic pressure and improve the efficiency of travel. It is important for the optimization of rail transit transfer in a special region. keywords: regional rail transit; synchronous transfer; travel time; departure timetable 作者简介：赵阳，电话：17615102857，邮箱：[email protected]。

Research on Crew Scheduling Problem Based on Time Space State Network and Lagrangian Relaxation
Zhang Zhe Ming，Wang Yin School of Traffic and Transportation, Beijing Jiaotong University
Abstract： Crew scheduling problem is a large-scale combinatorial optimization problem considering the ‘ mixing time ’ constraint. It is difficult to make use of the time-space network to solve. Therefore, this paper proposes recursion principle of time-space-state coordinates between adjacent two nodes and judgment method of feasible transformation between crew tasks as a network generation strategy which controls the network scale and reduces the model complexity to construct a time-space-state network. Then the paper establishes the network flow model base on time-space-state network and designs Lagrangian relaxation algorithm to divide multi-crew duties combinatorial optimization problem into a single-crew duty of time-space shortest path problem set. The solving efficiency is improved. Aiming at the characteristics of ‘strong symmetry’ and ‘overrelaxation’, this paper proposes the linear inequality constraints to break‘symmetry’and control ‘overrelaxation’ to accelerate the convergence of the algorithm and improve the quality of the lower bound. Finally, the model and algorithm are verified by an inter-city railway and the regional railway network experiment. The results show that this method could high-quality and efficiently solve the large-scale combinatorial optimization problem with ‘ mixing time ’ 14 constraints such as high speed railway crew scheduling problem. keywords:crew scheduling; ‘mixing time’ constraint; time-space-state network; network flow model; Lagrangian relaxation algorithm 作 者 简 介 ： 张 哲 铭 ， 北 京 交 通 大 学 交 通 运 输 学 院 ， 电 话 ： 17744412996 ， 邮 箱 ： [email protected]

Abstract：Installing longitudinal viscous damper on the one continuous unit of a continuous steel truss beam and flexible arch bridge, the paper studied the seismic response reduction performance of viscous dampers by nonlinear time-historic analysis. The paper discussed the influence of the parameters of viscous dampers on the structural seismic response from reducing the axial force of the arch springing, the internal force of pier bottom and the relative displacements between superstructure and piers. Then preliminary selected damping coefficient C and velocity index ζ with good damping effect compared with the seismic response in the case of no viscous dampers, finally set the viscous dampers at the full-bridge and analysed its damping effect. The results show that the axial force of the arch springing of the fixed bearing is significantly reduced after installing longitudinal viscous damper, but the axial force of the arch springing is increased individually at the top of the movable pier. When ζ is constant, the damping effect is more obvious with the C increase. The relative displacement between superstructure and piers at the top of the movable pier decreased with the decrease of ζ and the increase of C.The paper selected the damper parameters then setting the viscous dampers at the full-bridge by taking one continuous unit of a continuous steel truss beam and flexible arch bridge as the research object. The results show the maximum positive damping rate of the full-bridge is 76.55%, and the maximum negative damping rate is -21.40%. Although there are some negative damping rates in some locations after set the viscous dampers on the full-bridge, their seismic response of the full-bridge is still the smallest. The viscous damper effectively improves the damping effect of the full-bridge.

16 A Computational Graph Approach for Identifying Trip Generation, Destination Choice and Mode Choice
吴丹婷 北京交通大学交通运输学院 [email protected]
Abstract：Travel demand is one of the fundamental inputs for transportation planning models to evaluate current/future network states. Nowadays, the emergence of multi-source heterogeneous data such as cell phone data, parking lot survey data, transit IC card data and sensor data provides a new opportunity to estimate origin-destination (OD) demand in a much more reliable way. Besides, machine learning has become a new solution to complex models and algorithms as the research progresses. This paper proposes a computational graph approach for multi-modal traffic demand estimation using various sources of heterogeneous data. First, a hierarchical feed-forward framework based on gravity model and logit model is built for multi-modal demand estimation. Further, for backward parameter calibration and estimation, we use a computational graph combining multi-source big data in four layers which are the trip generation layer, trip distribution layer, multi-modal trip distribution layer and link layer. For better illustration of the proposed methodology, one hypothetical example is tested based on TensorFlow and large-scale experiments based on the transportation network in Beijing with multi-source real sample data are implemented for further demonstration and validation.

For the modelling of the shape, the next generation Korean high-speed train named HEMU-430X has been used. Based on the calculated flow fields around the train, the total aerodynamic drag as well as the drag due to each sources have been analyzed. The results show that the pressure drag especially by the roof housing of the vehicle is the most important drag source of the high-speed train and the ratio of the skin friction drag to the total aerodynamic drag is relatively smaller than that of modern high-speed train. Key words：high-speed trains, aerodynamic drag, computational fluid dynamics

Abstract：It has been about 5 years since One Belt and One Road was unveiled in 2013. Under the leadership of China president Xi Jin Ping, with the focus on connectivity and cooperation between Eurasian countries to bridge the infrastructure gap and accelerate economic growth across Asia Pacific and Central and Eastern Europe, many important projects of , railway and highway, automobile, real estate, power grid etc have been launched in many countries. However, not many One Belt and One Road projects of railway have been invested in Vietnam due to the lack of survey and studies focusing on this area. As an S-shaped country in Southeast Asia, a neighbor country of China, Vietnam will be a lucrative market right in the center area of the railway investment competition among Europe, China, and Japan. This is clearly shown in many researches and articles such as Europe Faces China, Japan in High-Speed Rail Battle in Asia by Srinivas Mazumdaru - February 15, 2018,“A Tale of Two Rail Lines”China and Japan’s Soft Power Competition in Indonesia by Ann Listerud - May 12, 2017 and High-speed Railways and Sino-Japanese Rivalry in Southeast Asia by Dragan PAVLIĆEVIĆ and Agatha - November 9, 2016. We, Vietnamese side, are well aware of this important chance for a win-win cooperation to modern our railway system. This research will show the existing conditions and our expectation for railway system in Vietnam. Moreover, based on this research, there would be more considerations of further investment to Vietnam railway market in the future.

Wang Wen Cong，Wang Chun （1.上海市城市建设设计研究总院（集团）有限公司，2.杭州市交通规划设计研究院）
Abstract： With the rapid development of China's high-speed railway (HSR), the “ space-time contraction” effect of HSR will change the regional traffic accessibility. Traffic is the important engine of pulling regional economic development, so it is necessary to explore the accessibility status of HSR in different cities both on regional and metropolitan dimension. Typological study is the basis for other related studies. In this paper, taking 48 HSR stations in 41 cities in China, we studied the location characteristics and then a Two-step Cluster analysis is made with the location potential value and average travel time. We found that the HSR stations can be classified into three clusters. The method and conclusion in this study could help urban planners and policymakers make a further analysis on the planning and construction of HSR stations. keywords: High Speed Railway Station; Reachability; Classification 作者简介：王文聪，上海市城市建设设计研究总院（集团）有限公司，电话：18801784238， 邮箱：[email protected]

蔺鹏臻 兰州交通大学 [email protected]
Abstract ： Based on the theory of 3D unsteady turbulence and dynamics of rigid-flexible multi-body system, a railway train-bridge interaction model is established, the air pressure pulse is taken into account, in order to analyze the influence of wind load to the train-bridge system when two high speed trains meeting on the bridge. A 40m freely supported beam bridge model is created, which will probably be used for higher speed railway in future. Safety, ride comfort, displacements, impact coefficient, accelerations and other dynamical variables are analyzed during the numeric simulation. The results show that the dynamical responses of train and bridge increase with the speed, except that the vertical displacement of bridge, which firstly decreases and then increases as the speed increases. The pressure of wind has much more influence on the vertical responses of train than lateral responses, and little influence to the bridge. Taking lateral acceleration and Sperling index as safety criteria for train, the maximal meeting speed for high speed trains on bridge is 450km/h. Considering the high-speed trains passing on the bridge, the impact factor of the bridge will be greater than that of the existing standard.

Optimization of the Number of Automatic Ticket Checkers for Urban Rail Transit Station
Liao Ding Fang Abstract： The gate ( automatic ticket checker) of urban rail transit station is the node for passengers entering and out of the pay area of stations, and the number of the gate is an important factor affecting the operation efficiency of the stations. The process passengers enter or out of the gate in the urban rail transit is a queuing service process of multi service platform and multi queue. According to the queuing theory, the queuing process is simplified as multifarious single channel waiting queuing systems in this paper. Then, the queuing situation in the peak time of the station check gate system is analyzed. Considering the economy and service efficiency of the system, the optimization model of gate number is built, and by comparing the gate throughput capacity and the station, to verify the increased gate would cause the passengers stranded in the platform, leave hidden dangers. Finally, this paper give a practical example of Xi'an Metro Line 2 Nan ShaoMen station intake gate system to verify the evaluation mode. The optimization result is when the number of the intake gate is increased from 6 to 7, the benefit of the station intake gate system will reach the maximum. key words: urban rail transit, number of the gate, queuing theory, optimization model 作者简介: 廖定芳，长安大学，电话：18109283132，，邮箱：[email protected]。

Sun Xian Fu,Shi Jin,Xu Ping,Gao Ya
Abstract： A Chinese standard EMU vehicles - line dynamic analysis model was established based on vehicle-track coupled dynamics theory. The matching relationship between curve radius, superelevation and vehicle speed was studied at a higher speed from the point of safety and comfort. A dynamic calculation analysis of Jinan-Qingdao high-speed railway has been done. The research shows that: (1) The recommended value of minimum curve radius is 9 000 m when speed is 400 km/h, the recommended value is 8 000 m under normal conditions and the recommended value is 7 000 m under difficult conditions. The design superelevation is 175mm. (2) Running 400km/h high-speed trains on a high-speed railway achieved the demand of safety and the comfort of train body vibration acceleration. The horizontal Sperling index and ISO2631 in low frequency vibration has declined. (3) By comparative analyses. ISO2631 has considered the influence of low frequency vibration acting on for passenger compared with Sperling index and UIC513, its evaluation criteria are more stringent. The traffic safety index frequency statistics can reflect the dynamic effect of train on track under different speed and different line conditions. keywords:400km/h high-speed railway; line parameters match; dynamic simulation; safety; comfort 作者简介:孙宪夫，北京交通大学，电话：18811771715，邮箱：[email protected]。

Vibration Characteristics of Pile-Group Foundation Based on TLM-PML-VM Method
Cao Yan Mei,Wu Pan
Abstract： The Green’s function of layered subsoil displacement is derived by adopting the Thin Layer Method (TLM) and Perfectly Matched Layer (PML). And the TLM-PML method is applied in a study of foundation soil in and out of two-dimensional plane. A dynamic analysis model of pile group foundation with pile caps and foundation soil is established according to the principle of Volumetric Method (VM). Based on the model, a dynamic impedance function of pile cape and pile group foundation is deducted by adopting TLM-PML method. Then, an analysis of pile group foundation’s dynamic impedance in layered-soil is carried out. What’s more, a comparative study of the influence of subsoil’s shear wave velocity, pile spacing effect to pile group foundation’ impedance from horizontal direction and vertical direction is conducted. The conclusion can be reached out that: when the distance between piles is small, the dynamic interaction of pile and soil is not evident and the dynamic impedance function of pile group foundation does not fluctuate with the change of frequency. And when the distance between piles is large, the dynamic impedance of the pile group foundation shows a strong correlation with the change of frequency domain, and the dynamic stiffness and damping of piles foundation displays variation with the
27 change of frequency. When the pile placing is fixed, there is a positive correlation between the peak frequency and the shear wave velocity of pile group foundation.

Abstract：The opinions on large-scale metropolis rail transit network planning, design and operation vary the transit systems geometric shape and service strategies, which influence future patterns of urban development and metropolis’ economic gravitation. Studying the evolution of rail transit network in cities can provide valuable lessons for new projects, including the choice of appropriate transit modes and the design of network efficiency. Digesting the historical land use theories from distinguished experts, a critical topic has not yet been discussed. That is, how could a through-running station and a regional unified network (RUN) generate long-term sustainable economic growth for the cities and metropolises. This article focuses on the comparison of through-running vs. dead-end rail operations within the central business district (CBD). The analyses focus on three components of network design. First, the definition, measures, and decision-making trade-offs are well-interpreted. These guidance could be applied to an evaluation of network efficiency for medium capacity modes and metros in metropolitan areas and regional rails in metropolises. Second, the time-distance measure shows two independent concepts of static and dynamic transport units (either vehicles or persons) on a common variable, allowing network experts and operators to precisely define the minimal headway of leading and following trains. The reduced headway lowers the deadhead non-revenue operating time to further increase fleet utilization. There is a positive correlation between network efficiency and metropolis’ long-term economic competiveness. Third, a series of comparison analyses of several international case studies across independent vs. integrated lines; trunk vs. feeder lines, through-running vs. dead-end operations on metros and regional rail systems are presented. It is, now, time to pay systematic attention to the planning, design, and operation of efficient regional unified network.

Model and Algorithm for Train Platform Scheme Rescheduling at High-Speed Railway Hub Station
Ning Jia，Lu Gong Yuan
Abstract： The hub station connecting multiple high-speed railways needs reasonable arrange- ment of platforms for multi-direction trains and is required to ease the route conflicts in the operation. Making reasonable train platform rescheduling instantly after interference guarantees train operation order on the connected high-speed rails. The decision-making of train platform scheme rescheduling needs to meet the requirements of real-time, executability and safety. Under the premise of integrated optimization of platforms and routes in the throat, in order to minimize the impact on train delay and station operation, the mixed integer linear programming model was established. In which the problem was decomposed into two subproblems: the train platform allocation problem and the arrival and departure time rescheduling problem, and the algorithm framework based on branch and bound algorithm was designed. The best adjustment was obtained in the test experiment of 12 arrival and departure tracks and 84 trains under the interference, which further verifies the validity of the model and the algorithm. keywords:high-speed railway hub station; conflict resolution; train platform scheme rescheduling; linear programming; branch and bound algorithm 作者简介:宁佳，西南交通大学，电话：18215632400，邮箱：[email protected]。

曹容宁 北京交通大学 [email protected]
Abstract ： Compared with traditional passenger trains, environmental vibration property induced by freight trains is significantly different due to vehicle types, vehicle marshalling, load capacity and operating speed. Freight trains may cause more vibration effects on sensitive targets along railways. To compare the dynamic property of vibration source and environmental vibration, the coupled vehicle-rail model was established in frequency domain based on the periodic theory. According to the transfer matrix, Fourier integral transform and coordinate transformation methods, the vehicle-track model was excited by the moving load. Dynamic loads acting on the fasteners of four vehicle types (passenger train YZ22, freight train C62A 、 C70 、 C80) were obtained. Based on the track-soil finite element model, the train-induced ground vibrations were analysed in the time and frequency domains. The calculation results show that: the dynamic load acting on fasteners caused by wheel-rail interaction is significantly different due to the different train type. With the increase of axle load, the low-frequency vibration and environmental vibration become lager. The greater the axle load is, the farther the vibration wave propagates.

Abstract：It is an effective method to control the rail vibration noise from the sound source. In order to research the vibration and noise performance of damping rail，a standard rail and a damping rail are taken as the research targets. Firstly, using the 2.5D finite element method to build damping rail, considering the effect of rail fastener, applying the vertical unit harmonic load on the upper part of the damped rail as a response to obtain the vibration response of the rail surface, using acoustic wavenumber in boundary element method to calculate the acoustic radiation characteristics. Analysing the influence of damping layer parameters on the vibration and sound radiation of damped rails. The results indicate that compared with the standard rail, the damping rail can effectively reduce the vibration and noise. Besides in the frequency domain, with the increase of the loss factor of the damping layer, the acoustic radiation reduction of the damped rail is more obvious. With the increase of the stiffness of the fastener of the damping layer, the vibration reduction of the damped rail is more obvious.

Abstract： Aiming at high-speed rail welding joint diseases ， a high-speed wheel-rail transient finite element model was established. Considering track-vehicle coupling dynamics and wheel-rail elastic-plastic deformations, the axle-box dynamic response of a high-speed train passing a rail welding joint was presented in both time and frequency domains. The response of axle-box vertical acceleration at bad welding joint is sensitive, it is suitable for the detection of rail welding joint state. The bad rail welding will cause the axle-box vibration at 240Hz and the PSD of it can be used to detect rail welding joint unevenness. The train speed of 400km/h meets the basic requirements with 0.1mm rail straightness at welding joint. When the speed is not more than 350km/h, it can be set to 0.2mm. If it is 0.3mm, the speed should be controlled below 250km/h. keywords:rail welding joint; high-speed wheel-rail contact; finite element analysis; axle-box acceleration 作者简介：于淼，中国铁道科学研究院，电话：18811735070，邮箱： [email protected] 。

In this study, the results of ANSYS numerical simulation was used to select five influencing factors including the distance from the center, buried depth of tunnel, elastic modulus of rock stratum, Poisson’s ratio, and rock density, and a back-propagation neural network model was established. Moreover, a BP neural network model consisting of five input neurons, one hidden layer, 11 hidden-layer neurons, and three output neurons was used to analyze and calculate the vertical Z-vibration level of New Capital’s ground buildings of Qingdao Metro phase I Project (line 3). The Z-vibration level under different working conditions was calculated from monolithic roadbed, steel-spring floating slab roadbed, and rubber-pad floating slab roadbed under the working condition of a center point of 0–100 m. The steel-spring floating slab roadbed was used in the New Capital area to monitor the subway operation vibration in this area. By comparing the monitoring and prediction results, it was found that the calculated results are less accurate and have a good linear relationship with the actual measured values. The research results have good reference and guiding significance for predicting vibration caused by urban subway operation.

Zhang Xiao Qiang Southwest Jiaotong Univercity [email protected]
Li Lin Southwest Jiaotong Univercity [email protected]
Abstract ： The profit of rail operators is related to the pricing policy and the operation planning. The operator’s pricing policy affects the demand, and demand is connected to profit. There are lots of researches on maximizing the profit of rail transport operator, most of which tried to optimize pricing or operation planning separately. As in fact, these two factors are connected with each other. The isolated research on either of them cannot get the optimal profit for operators. In this paper, a bi-level model is proposed, which integrate the pricing and operation planning, to maximize the profit of rail operator. The model includes a lower layer for minimizing the customer’s generalized cost, and a top layer for maximizing the benefit of rail operators. Simultaneously, the competition from road container transportation is considered in this model. An algorithm based on sensitivity analysis method was designed to solve this bi-level programming model. Numerical experiments have been made and the results prove the effectiveness of the proposed model. Key words：Rail Container Transportation；Operation Planning；Dynamic Pricing；Bi-level Model

Abstract：For evaluating efficiently the vibration response of the slab track in high speed railway, and based on the classical dynamic model for the track structure, slab track is simplified as an infinite long composite beam on the elastic foundation. Assuming that the dynamic response of the track structure subjected to periodic vehicle loads is periodic, the beam is truncated into a composite beam section with the length equal to a single vehicle by imposing periodic boundary conditions, a novel and efficient periodic model for evaluating track dynamic response was established. And then the spectral method was employed to solve the model, and the results were verified by finite element method (FEM). The calculation shows that the proposed model and method are of extremely high computational efficiency. Key words：High speed railway; Slab track; Spectral method; Periodic method

Abstract ： In order to study the rules of force and damage of broad-narrow joint under temperature rise, stress and damage parameters of broad joint and narrow joint under different conditions are calculated according to damaged plasticity model for concrete and cohesive zone model. Results indicated that the broad-narrow joint is in tension vertically and in compression longitudinally under temperature rise, which is the major cause of their damage. Through enhance the strength of the broad-narrow joint, the longitudinal force could be improved, but vertical force could not. Hence, compression damage could be reduced effectively, but tension damage could not. Through the increase of width of the broad-narrow joint, longitudinal and vertical force could be improved, so that compression damage and tension damage of broad-narrow joint could be reduced effectively.

Abstract：Asphalt concrete sealing layer (ACSL) has turned out to be an excellent integral waterproofing structure in word-wide railways. However, there is still a lack of research on the dynamic response of ballastless track with ACSL and there is no systematical method to determine design parameters for the special track system. Finite element models (FEMs) are established in this research to study the dynamic characteristics and influential parameters of this structure based on Zhengzhou-Xuzhou high-speed railway in China. The FEMs are verified to be appropriate by field test results. Compared to the track with the traditional concrete waterproofing layer, the major dynamic response in the track model including ACSL are smaller. That means ASCL has a positive effect on improving mechanical properties of the ballastless track system because of the viscoelasticity of asphalt concrete (AC). According to the impact analysis for the thickness of ACSL, the recommended thickness is 10~15 cm. Considering the influence of construction cost and mechanical properties, the modulus of the upper roadbed layer should be 100MPa.

Noise Prediction for Rail Bridges Based on Power Flow Method and Two-Dimensional Sound Field Model
Li Qi
（Department of Bridge Engineering, Tongji University）
Abstract： The force method in the frequency domain is applied to establish the compatibility equation of the vehicle-rail-bridge coupled system and to obtain the vibration power flows of the system. The two-dimensional (2D) finite-infinite element method is used to develop the vibroacoustic model for the rail and bridge system and to gain the sound pressure of given field points. The radiated noise from the rail-bridge system is then calculated by combining the sound radiation results per unit vibration power calculated from the 2D vibroacoustic model and the real vibration power of the rail-bridge system subjected to wheel-rail rolling excitation. The above noise prediction method is validated by both the field measurement and the statistical energy analysis (SEA) method. It is found that the two-dimensional (2-D) vibroacoustic model and the SEA model can predict the bridge noise very well, while the former one is more reasonable in the prediction of rail noise. keywords:rail transit bridge; train-track-bridge vibration; noise; power flow; finite element method 作 者 简 介 : 李 奇 ， 同 济 大 学 桥 梁 工 程 系 ， 电 话 ： 13764416395 ， 邮 箱 ： [email protected] 。

A Study of Snow Accumulation on Bogie of a High-Speed Train Based on Discrete Phase Model
Gao Guang Jun，Wang Jia Bin
Abstract： The operation of high-speed trains in ice and snow weather results in a large amount of snow accumulation with ice on bogie, which will seriously damage the safety of high-speed trains. In this paper, the accumulated snow on the bogie has been investigated using the numerical simulation method based on URANS Realizable k-ε turbulence model. The Discrete Phase Model (DPM) was used to investigate the snow particles’ trajectories, concentration and accumulation distribution around bogie region. The results show that the snow particles mainly flow under the bogie, only a small amount of snow particles turn back to the region above the bogie at the rear equipment cabin cover and windward surface of rear motor and axel, which leads to few snow accumulation on the upper surface of bogie. Lots of snow particles below the bogie directly impact the equipment of bogie, causing the massive snow accumulation on the bottom surface of bogie; and the accumulation amount on the bottom surface of bogie is far more than it on the upper. keywords: High-speed train; Bogie; Snow accumulation; Discrete phase model; Numerical simulation 作 者 简 介 : 高 广 军 ， 中 南 大 学 交 通 运 输 工 程 学 院 ， 电 话 ： 13875983049 ， 邮 箱 ： [email protected]。

Dynamic Identification of Wheel/Rail Contact Parameters and Its Application
Sun Shan Chao
Abstract： The wheel/rail contact parameters monitoring is very important to the derailment study and the safety assessment of high speed railway. For the purpose of the railway safety, based on the property of the vehicle/track system, using the theory of the vehicle dynamic, this paper establish an nonlinear wheel/rail contact force identification model by applying creep theory to load identification. The nonlinearmodel is discretized by Newmark- method, and is solved by chord section method. Therefore the lateral displacement of the wheelset relative to the track and the contact parameters are obtained. The identification results are compared with the simulation model and the verification results show that: the correlation coefficient of the lateral displacement of the wheelset and simulation displacement is 0.71. This model needs only acceleration of the vehicle, and no extra displacement and track irregularity are needed. This model can compute efficiently and can be used widely in inspection vehicle and operating vehicle for operating safely. keywords: Creep theory；Contact parameters load identification；Comprehensive Evaluation 作者简介:孙善超，中国铁道科学研究院，邮箱：[email protected]。

Abstract ： Climate change and energy crisis have made rail transport more and more important. As of 2017, China's high-speed rail operation mileage reached 25,000 kilometers, passenger volume exceeded 1.2 billion passengers, four vertical and four horizontal high-speed rail network has been basically completed. Increasing competitiveness and expanding market share have become urgent problems to be solved in railway transportation. This paper analyzes the existing problems of high-speed railway passenger transport, analyzes the feasibility of introducing high-speed railway passenger revenue management. In the prediction of the demand of high speed railway passenger revenue management, there are "missing data" which lead to the fact that the real demand of passengers can not be fully reflected. In this paper, the concept of unconstrained demand in the aviation industry is introduced into the passenger transportation of high-speed railways, then constructed an unconstrained model of passenger demand for high-speed railways and adopted the EM-demand maximization algorithm to solve this problem. The gray neural network prediction method is based on unconstrained demand forecast, then obtained the demand forecast of different OD. According to the prediction results, the ticket allocation method based on O&D stock control is put forward. At the same time, the precise pre-division model and the fuzzy pre-division model are established, designing the PSO particle swarm optimization algorithm to solve the problem. Finally, an example is given to show that the ticket distribution method based on O&D nesting can bring some economic benefits to the railway department while meeting the travel demand of passengers.

Abstract：Railway passenger transportation involves a number of indeterminate risks on the passengers which can be brought about as result of the interaction of different complex elements within the railway system. In order to attain higher safety levels, managing these risks and reducing their effects is an essential requirement in passenger transportation services. In the pursuit to identify main railway passenger risks for Kenya railway transportation, this paper evaluates railway passenger risks by analyzing expert scoring results of railway passenger hazards based on the likelihood exposure consequences(LEC) method and grey system theory. A risk index degree is constructed for the 80 comprehensive hazards which were identified for the Kenya railway passenger transportation system. The hazards include eight risk factors (human (employees’, drivers’ and passengers’), equipment and infrastructure management, safety management, fire control management, environmental factors and operation risk factors). Grey relational analysis is used for analyzing and determining the extent of the influences among the risk factors in the system and their respective risk degree. The construction of the risk degree index provides the theoretical basis for the railway passengers’ risks management for the Kenya railway system and provides guidance for future risks investigation.

55 Can Line Extension Planning Mitigate Capacity Mismatch on Existing Rail Network?

朱亚迪 北京交通大学 [email protected]
Abstract：Operational planning in China is perhaps more important today than ever before owing to the ongoing expansion of urban rail in the country. As urban rail networks becomes large and complex, new lines added to them significantly alter both their topologies and operational characteristics. The appraisal of alternative lines from the perspective of operation while planning is crucial. This study develops a method based on data embedded in the transit smartcards used in existing networks and the forecasted demands for new lines to assess the effects of planning for the addition of new lines on overcrowding in urban rail networks. Using the card data and forecasted demand, transfer demand at interchange stations and section load between stations can be estimated through the route choice model, and hence the influence of new lines on the operation of the network can be analyzed. The proposed method was applied to the case of a line extension to a network in Beijing, and the results revealed the reason for overcrowding on the original line: severe capacity mismatch due to poor planning. Moreover, the new extension effectively prevented overcrowding by shifting passengers’route choices with fewer interchanges. Approximately 63% of passengers desiring an interchange on the target line altered their interchange from the station that had acted as bottleneck to the new interchange. Thus, a capacity mismatch was avoided, and the headway of the feeding line was reduced from 6 min to 3.5 min. Hence, the capacity mismatch problem no longer occurred.

Study on the Selection of Similar Days in the Passenger Flow Prediction of Urban Rail Transit
Guang Zhi Rui,Zhang Yue Kun
Abstract： Choosing reasonable historical similar days is an effective way to improve the prediction accuracy of urban rail transit passenger flow. The paper proposed a method of choosing similar days to meet different demands of the passenger flow prediction. First of all, the passenger flow pattern of the date is defined, thus the process of choosing similar days has transferred into the process of pattern recognition. Secondly, similar days, after considering different demands of passenger flow forecast, are divided into two categories. And then, according to the above classification, two kinds of similar day selection algorithms are proposed respectively: one is "Forward day by day retrieval”, and the other is "Forward and backward positioning retrieval". Next, after considering the different characteristics of influencing factors , the paper proposed methods of quantitative transformation, normalization, and function construction to calculate the similarity degree of each influencing factor, such as temperature, wind force, weather condition, week attribute, holiday attribute and date distance. On this basis, the date similarity function, which contains the similarity of each factor, is constructed by a parameter dependent
58 multiplicative function. Finally, calibrated and validated by the historical passenger flow data collected by AFC system of Beijing Metro, the similar day selection model proposed in this paper is accurate and reliable, and of great value for improving the prediction accuracy of passenger flow. keywords:passenger flow prediction of urban rail trasit; the selection of similar days; weather factors; week attribute; function construction method 作 者 简 介 : 光 志 瑞 ， 北 京 市 轨 道 交 通 指 挥 中 心 ， 电 话 ： 18612483816 ， 邮 编 [email protected]。

Abstract ： This study aims to provide a robust strategy for predicting the time to the recurrence of rail defects at the same location by using the conditional frailty cox model. The model is built based on a US Class I railroad data from 2011 to 2016. The results show that the recurrence of a defect is highly correlated with different factors such as type of a rail defects, the location of that defect, train speed at the location of a defect, number of rail inspections between two successive defects, number of geometry defects in the last three years in the location of a defect and the type of remedy action. According to these results, several possible measures, such as applying more frequent rail inspections, reducing the train speed limit after the first occurrence of a rail defect, etc. can be considered to reduce the chance of recurrence of a defect on the same location. The results of this study are useful for railroads to develop effective strategies for track corrective maintenance to prohibit the recurrence of rail defects.

Abstract： The train plan is an important means to effectively utilize railway transportation facilities and to improve service quality of intercity railway. Based on the characteristics of time-varying demand, the space-time network method is involved into the train planning of intercity high-speed railway. The information of passengers’ departure time is considered in the optimization method and we can evaluate the train plan more comprehensively. Then upon the objective of minimizing the train running time, passengers travel time, penalty time of departure deviation and penalty time of passengers who didn’t board trains, a train planning optimization model is built. And a set of constraints including passenger flow and train flow conservation in time-space network, the station departure time interval, train capacity and total number of trains is necessary. A double layer simulated annealing algorithm is designed based on the characteristics of the problem. The inner layer algorithm optimizes train stop plan, the outer algorithm optimizes origin-destination stations, frequency and departure time of trains. Finally, through the calculation and analysis of the example, proves that the proposed method can provide scientific decision for train planning of

Noise Reduction Effects of Different Sound Barriers on Rail Transit Bridge
Zhao Qiu Chen,Li Xiao Zhen,Li Man,Zhou Fei Cong
Abstract： Noise pollutions produced by urban rail transit impact on residents along the line, which has drawn more and more attention. Setting sound barriers on both sides of the line is an effective measure to reduce the wheel-rail noise. Based on the statistical energy analysis method, the paper chooses a steel box composite bridge as research back ground, and establishes statistical energy model of vertical, semi-closed and fully-closed sound barrier by the noise analysis software VA one. Compare the equivalent continuous sound pressure level of field points, when there is no barrier and the one of the three different types of sound barriers is installed, to select the appropriate type of sound barrier for practical needs. Results show that the use of vertical sound barrier or semi-closed sound barrier can only effect on near-rail side noise reduction, while the total sound level on the far-rail side will increase instead of decreasing. For the near-rail side, the sound barrier has better noise reduction effect on where has same elevation as bridge deck on both sides of the bridge, but the effects get worse when the height increases. By contrast ,compared with the none noise reduction treatment , the equivalent continuous noise sound pressure level of the main building site can be reduced by about 15 dB (A),and fully-closed sound barrier can meet

(Chang'an University)
Abstract： With the construction and development of rail transit in major cities in China, its network structure has become more and more complex, it is difficult to intuitively determine the importance of a station (including transfer stations) relative to all other stations. This paper comprehensively considers the network structure characteristics, passenger flow intensity characteristics, and station attribute characteristics of the rail transit station, and adopts 6 indicators: node degree, node proximity, node intension, station passenger flow intensity, station traffic environment and location. The analytic hierarchy process is used to calculate the index values of each layer, and then the ideal point method is used to evaluate the importance of each site (except for the first and last station) in the entire network. Finally, taking the rail transit network in Xi’an as an example, the importance rank of each station (except the first and the last station) has been sorted out, which has certain reference significance for the rail transit management under the networked operation. keywords:urban rail transit, network structure, station importance, comprehensive evaluation model 作者简介: 李昕晏，长安大学，电话：18792707897，邮箱：[email protected]。

Research on Rail Pre-grinding Strategy&Growth Characteristics of Rail Defects in High-speed Railway
Zhou Yu,Zhang Cong Cong
Abstract： The development of pre-grinding new rail in high-speed railway was researched by simulation of wear and rolling contact fatigue (RCF) crack and field test. The effect of pre-grinding, defects of rail and their growth characteristics were analyzed. The results show the pre-grinding rail with special designed profile can control wheel/rail contact location and width of contact band to get excellent wheel/rail interaction. The main defect of pre-grinding rail is wear which had linear growth trend with the accumulation of operation time. The distribution of wear around the railhead in high and low rails was -10°~ 60° and ±10°respectively. After about 1 year operation, the special profile of high rail was changed by wear which deteriorated the wheel/rail contact condition and caused two-point contact in the high rail. It is recommended the preventive grinding interval is 1~1.5 years. keywords:Rail, wear, rolling contact fatigue crack, pre-grinding, preventive grinding 作者简介: 周宇，同济大学，电话：13818906532，邮箱：[email protected]。

Abstract ： The deformation of a bridge foundation (i.e. pier) of high-speed railway with ballastless track may cause additional irregularities, thereby impacting train operation. By using a unit-slab ballastless track-bridge system as the research object, this study built an interaction model with finite elements and train-track dynamics. The additional rail deformation caused by the vertical or lateral deformation of bridge piers were calculated by the finite element model, meanwhile the impacts for train operation due to the additional rail deformation were analysed by the train-track dynamic model. It was found that: 1) the lateral deformation of a single pier should be the most concern for the management and control of high speed railway. Specifically, the indices chosen for the evaluation of train operation were primarily affected by the magnitude of lateral deformation, but slightly affected by the vertical settlement when a pier suffered settlement and lateral deformation concurrently; 2) The impacts of length of concrete beams are also analysed. As for the situation that a high speed train passing a bridge built by 32m standard span concrete beams at 350 km/h, it will be within the limits of the safety and comfort indexes if the pier vertical settlement doesn’t exceed 20mm. However, if the pier lateral deformation exceeds 15mm, the safety index for high-speed train will exceed the limit value. Key words：High-speed railway, ballastless track, vertical/lateral deformation of bridge pier, safety and comfort of train operation

90 Time Effect of Pile-Soil-Geogrid-Cushion Interaction of RPCF under High-Speed Railway Embankments
王长丹 同济大学 [email protected]
Abstract：Centrifuge model tests were used to simulate pile-raft composite foundation and pile-geogrid composite foundation with different pile spacing for researching the time effect of negative skin friction of rigid piles in high-speed railways. The research results show that it is feasible to simulate the skin friction distribution of pile by centrifugal model test. The negative skin friction has a significant impact on the bearing capacity of composite foundation. Pile-raft composite foundation has higher bearing capacity compared to pile-geogrid composite foundation to reduce the effect of negative skin friction on piles. Both the foundation settlement and negative skin friction have significant time effect. The distribution of skin friction can be simplified as a triangle along the pile. The neutral point position moves deeper in the post-construction stage at larger pile spacing. The maximum negative skin friction usually takes place at the top zone of the piles. For pile-geogrid composite foundation, the setting of pile-cap affects the position of neutral point in the post-construction stage. Reinforced cushion with geotextile may promote the better performance of cushion for transmitting the loads to piles and surrounding soils. Arching effect in the cushion of the composite foundation is a progressive process. The compression of the rigid piles contributes less than 20% to 25% of the total settlement while the penetration of the piles and the compression of the bearing stratum below the pile tips contribute more than 70% of the total settlement. Some effective measures to reduce the settlement of soils need to be taken into consideration to improve the bearing capacity of pile foundation.

Abstract：This study investigates the application of tire derived aggregate (TDA) mixed with ballast material as an approach for improvement of the ballast track performance. In order to assess the TDA influence on the ballast layer, a series of ballast box tests were conducted on the mixture of ballast aggregates and 0, 5, 10 and 15% of TDA with the same gradation of the ballast size distribution. On the other hand, a series of numerical analysis was performed with the use of EDEM with the aim of the discrete element method simulation of the TDA-ballast mixture. Based on results, the settlement of numerical modeling and experimental tests were compared. While experimental results indicate that increasing TDAs percentage increases the damping ratio as well as the settlement of samples. Which is in a good agreement with the settlement of samples obtained from numerical analyses. In conclusion, the more use of TDAs mixed with ballast aggregates, the more settlement occurs which it can cause a disturbance to the interlocking of ballast particles.

Abstract：The increasing speed of high-speed railway has improved the requirements for the stability of high-speed railway subgrade. To ensure the quality of laying ballastless track on the subgrade, subgrade settlement deformation must be strictly controlled, especially to solve the settlement deformation problem existing in soft ground. Currently, CFG pile is the main pile type for soft soil foundation treatment of high-speed railway. However, there are few studies on the consolidation of soft rock foundation with CFG pile. Therefore, it is necessary to study the settlement law of soft rock foundation with CFG pile under high-speed train load. In this study, the numerical simulation was used to analyze the settlement deformation of soft rock foundation under high-speed railway with CFG pile. Then, the influence of different factors on the settlement of soft rock is analyzed through the change of vehicle speed, pile length, cushion thickness and material stiffness. Finally, the suggestions of using CFG pile to improve the strength of soft rock is given, which will provide some reference value for the settlement prediction of similar projects in the future.

Abstract：In order to simulate the erosion process of chloride ion in concrete box girder accurately, and obtain the concentration of chloride ion at arbitrary position at any time in the cross section and the prediction of durability life of the structure. Based on Fick's second law, a cellular automata model of concrete chloride ion diffusion was established based on the principle of 2D cellular automaton, which take the effect of material and age on the diffusion effect of chloride ion into account. According to the cellular automata model of chloride ion diffusion in the box girder, taking a box beam as an example, a MATLAB calculation program was compiled to analyse the diffusion rules of chloride ions in the cross section and to predict the durability life of the structure. The results of the study show that: Compared with the analytical solution of chloride ion concentration, the cellular automata model established in this paper can simulate the chloride ion diffusion process of concrete box girder effectively, and the calculation accuracy is high. According to the different forms of chamfered sections, chloride ions show different diffusion rules, and the time required for different concentrations of chloride ions to reach the critical concentration of steel corrosion is different. By comparing with the analytic solution of life prediction, it is proved that the model can effectively predict the durability life of concrete structures. The model is used to predict the service life of concrete box girder with chloride salt eroded environment, and the results show that the structure will reach the design limit of structure durability in service for 34 years.

Abstract：This study investigates suction profiles and structures of a compacted expansive clay (Maryland clay) in the compaction plane. Suction was monitored during the compaction, and it followed the main mechanical wetting path. This study showed that there was difference between the suction measured during the compaction and after unloading. The difference becomes more significant as degree of saturation increasing. The pore structures of compacted samples on the dry-side of optimum water content generally were all bi-modal structure, otherwise on the wet-side of optimum water were mono-modal structure. The intra-aggregate pore was independent on the maximum compaction stress, but its density and dominant entrance pore size gradually increased as water content increasing. For the inter-aggregate pore, its density and dominant entrance pore size decreased as maximum compaction stress increasing. | This study investigates suction profiles and structures of a compacted expansive clay (Maryland clay) in the compaction plane.

Abstract：The transition zone is a place where severe track settlement may occur, usually requires considerably more interventions to maintain the service quality and safety. Although lots of researches have been carried out, an overall consensus on the internal factors that trigger the deterioration of the tracks at transition zone is still under investigations. To further probe into the deterioration of track geometries in transition zone, a field test was carried out to measure the wheel-rail force, rail seat loads and track component’s dynamic response in Sui-Yu railway line. Moreover, a numerical model that couples Discrete Element Method (DEM) with Finite Difference Method (FDM) is proposed to survey dynamic behaviors of the transitions. The results show that: the results of model calculation are consistent well with the experimental results.

Effects of Spatial Variability on Settlement of Composite Foundation of High Speed Railway
Zhang Jie
Abstract： Composite foundation is often utilized to reduce the post-construction settlement of high speed railway embankments constructed on the soft soil. Due to the uncertainties in the properties of the soft soil and mixed columns, the settlement of the composite foundation is also uncertain. To consider the influence of the spatial variability on the settlement, the finite difference method is used to predict the settlement of an embankment supported by the DM columns. Both spatial variability and complex interaction between soil and columns can be considered by the random field finite difference method. Sensitive analysis is conducted to the random variables investigated in this study. Effect of the spatial variability on the settlement happened during the construction period is studied, and the effect of the spatial variability on the maximum post-construction settlement is also investigated. keywords: Random field, high-speed railway, composite foundation, settlement 作 者 简 介 : 张 洁 ， 同 济 大 学 地 下 建 筑 与 工 程 系 ， 电 话 ： 18801736218 ， 邮 箱 ： [email protected]。
108 Dynamic Behaviors of Railway’s Base Course Materials Subjected to Long-Term Low-Level Cyclic Loading
Abstract ： The aim of this research was to develop a practical method for estimating the dynamic elastic modulus and accumulated plastic strain of a railway ’ s base course materials subjected to increasing long-term, low-level cyclic loading. For this purpose, two series of cyclic triaxial tests, one with single-stage and the other with multi-stage loading were performed. It was found that the accumulated plastic strain increased as the number of cycles and amplitude of the loading increased, but that the permanent strain decreased as the confining pressure becomes higher, and appeared to be closely related to the stress history. Considering the effect of the stress state, an empirical model was proposed to predict the accumulated plastic strain. Then, the model was modified on the basis of the time hardening approach. In this way, permanent deformations in various stress stages were accumulated using an equivalent number of load cycles. There was good agreement between the predicted and measured deformation.

Abstract：The prediction model of FE bridge structure and FE-SEA hybrid bridge structure is established by using a frequency-dividing strategy. The frequency domain and characteristics of the vibration and structural noise of the U-beam within the 1.25Hz~250Hz frequency range, when subjected to a vertical wheel-rail interaction force,were analyzed. Then some relevant conclusions are acquired that: (1) Under the action of wheel/rail force, the frequency with the maximum amplitude in the spectrum of vibration and structure noise of a U-beam is mainly concentrated in the range of 31.5~80Hz. (2)The structure noise at the far-field point and under the bridge point is mainly affected by the sound pressure of the bottom plate. Therefore, the bottom plate should be the main object for noise reduction. (3)And the sound pressure level of the field also has a large peak value, at the low frequency about 4Hz. The method used in this paper can greatly improve the running efficiency while guaranteeing a better precision, which can provide reference for the vibration and noise reduction of the bridge in the actual project.

Abstract ： A transportation system consists of many spatially and temporally distributed demand and supply factors, each with different degrees of connections with each other. This paper aims to describe the inherent connections among various factors in the context of system optimization. Specifically, a computational graph based modelling framework is used in this paper to represent the topological structure of a transportation system to be optimized. The sequential optimization steps can be described as a feedforward process in the proposed computational graph framework and the estimation procedure can be described as a back propagation process. We can accordingly compute and capture how the marginal cost from different layers transfer between interconnected elements in a computational graph. We also review the gradient based methods to represent the marginal cost in an estimation process, by following the naturally inherent hierarchical structure in the representative transportation system. By reviewing the gradient methods used in a closely connected optimization (traffic assignment) and estimation (OD matrix estimation) transportation problems, we offer further insights on how different factors interact through the gradient mechanism within the computational graph modelling paradigm. Comparisons between the computational graphs with the commonly used neural network are provided to shed more lights on future large-scale transportation system optimization applications.

Using the blackboard communication mechanism of multi-agent, a train intelligent dispatch simulation model of single-track railway network was established. With the help of Anylogic, this simulation model was applied to an actual single-track railway network in Southwest China and the simulation results showed that the proposed conflict resolution and deadlock protection mechanism can guarantee the effectiveness of train operation dispatch on single-track railway network. It showed that multi-agent simulation is an effective method to achieve intelligent dispatch on single-track railway network.

Abstract： A dynamic image-grey template matching method was proposed to identify the catenary suspension point movements for wind-induced vibration issue of railway catenary system in Nanjiang wind area. The catenary positioning point was chosen as the target matching template, which was compared with equal-sized concerned area sequentially by using the proposed root mean square (RMS) matching operator regarding pixels grey. And 3-D contour map of grey-matching operator value at each sub-area in comparison with target template was obtained, where the target pixel coordinates were determined according to the minimum RMS matching operator value. Considering the complex imaging environment, the target template was updated by the detected target area after each matching, to make the target recognition algorithm immune to
126 both variable environment brightness and contrast. Furthermore, to eliminate detecting errors due to observing datum movement, both static background template and dynamic target template were identified simultaneously for acquiring the absolute motion of the target. Finally, validity of the proposed recognition algorithm was verified through camera observation when a target object is moving along a given path and camera vibrates during the process. The calculated target motion is in good accordance with the given theoretical motion, where the relative errors between them vary within 1.8%. Validation results indicate that the dynamic template matching method can realize wind-induced catenary motion recognition in complex imaging environment, and thus provide an effective methodology for wind vibration study of catenary suspension system on the basis of meeting the request of engineering precision. keywords: Railway catenary; sand distribution characteristic; train-set; Lanzhou-Xinjiang railway for passenger traffic 作 者 简 介 : 周 伟 ， 中 南 大 学 交 通 运 输 工 程 学 院 ， 电 话 ： 13975126342 ， 邮 箱 ： [email protected]。

Abstract：Sealing the tunnel entrance is one of tactic for railway tunnel firefighting. In order to understand the effect of tunnel entrance sealing ratio on fire behavior, Computational Fluid Dynamics (CFD) is used to simulate tunnel fire with different heat release rates and sealing ratios varied from 0% to 100%. Both the maximum temperature and the temperature distributions along the tunnel ceiling were focused on and compared with previous experiment data and calculated values using the empirical model. Results show that the ceiling temperature increases with sealing ratio due to the heat accumulation inside the tunnel when the heat release rate is relatively small. Moreover, the longitudinal ceiling temperature decreases with sealing ratio increase and then tends to stability due to less oxygen supply when the heat release rate is relatively large. The maximum longitudinal temperature beneath tunnel ceiling decreases exponentially with the distance. The correlations determining the maximum temperature and temperature decay beneath the tunnel ceiling are proposed to modify the current model by taking the tunnel entrance sealing ratio into account. The predictions by the modified equations of this work agree well with the experimental and measured data. Key words：Tunnel fire; Sealing ratio; Maximum temperature; Longitudinal decay; Tunnel ceiling.

Abstract：Turnout is the essential equipment on the railway, which also belongs to one of the strongest demanded infrastructural facilities of railway on account of the more seriously frog rail failures, which are the results of the crack growth. So far the classification of the rail failures has been already qualitatively described in UIC Leaflet 712 R in details. Our research team is dedicated to the quantitative analysis of the superficial abrasion and the internal damage below the running surface in cooperation with Germany Railway Company (DB Netz AG) that provides us with a large amount of measured records. On the basis of the measurement, the damage degree of the running surface is calculated according to theories of the contact mechanics and strength of materials. The growth of the superficial abrasion experiences three stages with the different abrasion rates, while the internal damage below the running surface increases linear all the time. Finally, the interactions between the abrasion rate and the internal damage as well as the breakage on the running surface are briefly discussed for the service lifetime of the frog rails in combination of the determined dynamical loads.

Research on Intelligent High-Speed Train Operation Simulation Based on Cellular Automata Theory
Feng Xiao,He Shi Wei,Li Yu Bin
Abstract： Cellular automaton theory is one of the important tools for microscopic simulation, but the potential of this method has not been fully explored in the field of railway simulation. Part of the reason for this phenomenon is improper simulation granularity selection. This paper reselects a more reasonable simulation granularity, so that it can reach a balance between simulation calculation scale and simulation scale. On this basis, this paper simulates a route that includes multiple stations and sets up arrival and departure sidings for each station. The simulation results show that the simulation granularity selected in this paper can simulate the mobile blocking system better and avoid some of the deficiencies in other similar researches. keywords:Moving–block signaling system; Cellular automaton; High speed railway 作者简介: 冯骁，邮箱：[email protected]。

Lu Gong Yuan,Zhang Bo Jian,Li Li,Peng Qi Yuan
Abstract： Shunting operation plans of trains detaching and attaching is one of the classic questions in the transportation organization of freight train. Considering the coupling and decoupling process of flat shunting operation，an 0-1 programming model was established to minimize the total trips of operational quantities. The model takes the initial status and the termination status of vehicle as input variables and takes the shunting operation plan as output. The shunting operation plan experiments showed that without considering the position of coupling by dispatchers, the solution of the model can get the minimum total trips of coupling just as effectively as with the orchestrating-suit method. Besides, the solution can get the number the minimum total operational quantities. The results show that compared to the orchestrating-suit method, the model can reduce the total operational quantities. keywords:Integer Programming；Trains Detaching and Attaching；Shunting Operation Plans 作者简介: 鲁工圆，西南交通大学交通运输与物流学院，电话：13880609100，邮箱： [email protected]。
