The Influence of Buildings and Ground Stratification on Tunnel Lining Loads Using Finite Element Method
The influence of buildings and ground stratification on tunnel lining loads using finite element method L'influence des bâtiments et de la stratification du sol sur les charges de revêtement du tunnel utilisant la méthode d’éléments finis Rezaei A.H. Ph.D. student, Faculty of Civil Engineering, University of Tabriz, Tabriz, Iran Katebi H., Hajialilue-Bonab M. Associate Professor, Faculty of Civil Engineering, University of Tabriz, Tabriz, Iran Hosseini B. M.Sc in Geotechnical Engineering ABSTRACT: Urban development and increasingly growth of population have been accompanied by a considerable growth in mechanized Shield tunnelling. Commonly precast concrete segments used as tunnel lining in mechanized tunnelling and include relatively considerable part of tunnelling cost. The optimum design of lining that decreases tunnelling cost needs to accurate evaluation of loads act on lining. In this study, the effects of soil stratification, building’s geometry, position and weight on lining loads were studied. A 2D finite element model was applied to simulate the conventional procedure of tunnel excavation and lining using Abaqus software (Ver 6.10). The geometry of tunnel, lining segments, injection grout and around soil properties were adapted from under construction Tabriz urban railway line 2 project. The results show that ground stratification and building properties (especially the position of buildings) have considerable effects on lining loads. From the viewpoint of structural design, the buildings effect on lining is critical when the surface buildings are unsymmetrical. RÉSUMÉ : Le développement urbain et de plus en plus la croissance de la population s'est accompagnée d'une croissance considérable dans le domaine de Tunnelier. -

Case Study Tabriz of Metro Single Tunnel
Designing and Optimizing Support System - Case Study Tabriz of Metro Single Tunnel A.H. Ghazvinian K. Goshtasbi N. Ghasempour Tabriat Modares university, Mining Engineering Department, Iran E-mail: [email protected] ABSTRACT The designers need engineering judgment to select the optimum option among the alternatives. The optimum choice can be selected by the expert engineers taking into account their judgment and immediate insight. Nowadays, decision-making methods can help engineers to support their decision in the scientific way. The Analytical Hierarchy Process (AHP) is a decision making method and is a branch of multi attribute decision-making (MADM) methods utilizing structured pair-wise comparisons. This paper presents an application of the AHP method to the selection of the optimum support design for the Tabriz Urban Railway(TUR) tunnel line no 2, which has been planned for transporting passengers from vali-Asr Square to Gharamalek State in Tabriz, Iran. The methodology considers five main objectives, namely: displacements in the roof and bottom of the tunnel, the factor of Safety (FOS), the economic and possibility factor for the selection of support design. The displacements and stress values were obtained by using the finite difference program, FLAC3D as the numerical studies have been widely used by the engineers examining the response of any opening in underground, in advance. After carrying out numerical models for different support design, the AHP method was incorporated to evaluate these support designs according to the pre-determined criteria. The result of this study shows that the AHP application is a good tool to effectively evaluate the support system alternatives for underground cavities. -

Of Geotechnics Engineering, Faculty of Civil and Environmental Eng., Tarbiat Modares University (Tehran, Iran), email: [email protected] Aliakbar Golshani, Associate Prof. Geotechnics Engineering, Faculty of Civil and Environmental Eng., Tarbiat Modares University (Tehran, Iran), email: [email protected] Sina Arefizadeh, M. Sc. Of Transportation Engineering, Faculty of Civil and Environmental Eng., Sharif University (Tehran, Iran), email: [email protected] ABSTRACT: The current study is aimed at investigating the basic soil behavior involved in a TBM-EPB excavation and the capability of the Modify Cam Clay (MCC) model is verified for the analysis of the soil settlement in cohesive soils. Tunnel excavation in urban areas can engender considerable ground movements, which is known as one of the complicated issues that may have negative effects on the extant structures. In this paper, the construction of the second line of the Mashhad metro is considered as a case study. Each section of the ground was modeled by two constitutive models, namely MCC and Mohr-Coulomb (MC). Afterwards, the results of numerical analyses and monitoring data were compared with each other. In addition, real parameters of soil, such as volume loss and the inflection point, were obtained via empirical approaches verified by tunnel monitoring. Numerical modeling was performed by FLAC3D software. Based on the transverse and longitudinal sections settlement, the MCC model showed high capabilities of predicting the surface settlement in comparison to the MC model. -

A Comprehensive DC Railway Traction System Simulator Based on MATLAB: Tabriz Line 2 Metro Project Case Study
Journal of Operation and Automation in Power Engineering Vol. 9, N o. 2, Au g. 2021, Pages: 144-159 http://joape.uma.ac.ir A Comprehensive DC Railway Traction System Simulator Based on MATLAB: Tabriz Line 2 Metro Project Case Study S. Razmjou Department of Management, Faculty of Economics, Management, and Business, Tabriz Campus, University of Tabriz, Tabriz Iran. Abstract- As a result of rapid global urbanization, energy and environmental sustainability are becoming increasingly significant. According to the Rail Transport and Environment Report published by the International Union of Railways in 2015, energy used in the transportation sector accounts for approximately 32% of final energy consumption in the EU. Railway, representing over 8.5% of the total traffic in volume, shares less than 2% of the transport energy consumption. Railway plays an important role in reducing energy usage and CO2 emissions, compared with other transport modes such as road transport. However, despite the inherent efficiency, the energy used by the rail industry is still high, making the study of railway energy efficiency of global importance. Therefore, in this paper, the development of the comprehensive simulator software for DC-fed railway systems is demonstrated. In the proposed MATLAB based software, the train movement model and railway power network model are integrated into the simulator. This energy simulator can calculate the energy flow of the whole system according to multiple-train driving controls and timetables. Finally, the results of simulations -
