Page 1/2 The S-shaped Hangzhou Bay Bridge is an important connection in China’s East Coast Superhighway. Starting in Jiaxing to the north, the bridge ends at Ningbo’s Cixi county in the south. The 36 km long Hangzhou Bay Bridge is the longest ocean-crossing bridge in the world, spanning across It shortens the ground transportation distance from Ningbo the Hangzhou Bay on the East China Sea and crossing to Shanghai by 120 km and travel time from four hours to the Qiantang River at the Yangtze River Delta. It two and half hours. It is a six-lane, two-direction highway surpassed the Donghai Bridge, the longest transoceanic with a 100 km/h speed limit, and a 100 year, service bridge in the world, when it was opened in 2005. guaranteed, cablestayed design. Fibertex Nonwovens A/S has supplied approximately 36,000 m² CPF Formtex® to this project during the construction period of 2004 and 2005. Fibertex Nonwovens A/S was chosen as supplier due to the company’s experience as a supplier to major constructions around the world and due to the company´s flexible installation system. For this project mainly steel forms were used and hence the gluing method of installation was chosen. On top of this it was required to install both on forms placed horizontally and vertically.

Author manuscript, published in "Journal of Transport Geography 25 (2012) 58-69" New port development and global city making: Emergence of the Shanghai-Yangshan multilayered gateway hub Chengjin WANG Key Laboratory of Regional Sustainable Development Modeling Institute of Geographical Sciences and Natural Resources Research (IGSNRR) Chinese Academy of Sciences (CAS) Beijing 100101, China [email protected] César DUCRUET French National Centre for Scientific Research (CNRS) UMR 8504 Géographie-cités F-75006 Paris, France [email protected] Abstract Planned as Shanghai's new port, Yangshan is currently expanding its roles as transhipment hub and integrated logistics/industrial center in the Asia-Pacific region. This paper examines the impact of the emergence of Yangshan on the spatial pattern of the Yangtze River Delta since the 1970s, with reference to existing port system spatial evolutionary halshs-00717879, version 1 - 13 Nov 2012 models. While this emergence confirms the trend of offshore hub development and regionalization processes observed in other regions, we also discuss noticeable deviations due to territorial and governance issues. Strong national policies favoring Shanghai's vicinity rather than Ningbo as well as the growth of Yangshan beyond sole transhipment functions all contribute to Shanghai's transformation into a global city. Keywords: Asia; China; corridor; offshore hub; port system evolution; urban growth; Yangtze River Delta 1 1. Introduction Throughout the literature on port cities, a majority of the research provides a separate discussion on either port or urban functions. Port and urban specialists often focus on what may appear as processes and actors of distinctly different nature. One example is the large body of research on so-called port systems where neighbouring port nodes go through successive development phases marked by varying traffic concentration levels.

SHOCK CONTROL of BRIDGES in CHINA USING TAYLOR DEVICES’ FLUID VISCOUS DEVICES 1 1 2 2 Chen Yongqi Ma Liangzhe Cao Tiezhu1 Robert Schneider Craig Winters
th The 14 World Conference on Earthquake Engineering October 12-17, 2008, Beijing, China SHOCK CONTROL OF BRIDGES IN CHINA USING TAYLOR DEVICES’ FLUID VISCOUS DEVICES 1 1 2 2 Chen Yongqi Ma Liangzhe Cao Tiezhu1 Robert Schneider Craig Winters 1Beijing Qitai Shock Control and Scientific Development Co.,Ltd , Beijing 100037, China 2Taylor Devices, Inc. North Tonawanda, NY 14120, USA Email: [email protected], ABSTRACT : Fluid Viscous Devices are a successful structural protective system for bridge vibration. The structural protective technique and the dampers have been introduced to China since 1999. The Taylor Devices’ damper systems has already been successfully installed or will be installed in large or the super large bridges in China for protection from earthquake, wind. vehicle and other vibration. Seventeen different bridge projects introduced here include the Sutong Yangtze River Bridge, the longest cable stayed bridge in the world, the Nanjing 3rd Yangtze River Bridge, the fifth longest suspension bridge in the world, and the Xihoumen Across Sea Bridge, the second longest suspension bridge in the world. The performance of the bridges and dampers have been reported as “very good” during the May 12, 2008 Wenchuan earthquake. All of the dampers produced have been subjected to rigorous static and dynamic testing, which show the dampers will perform well for the next 50 years and possibly a lot longer. KEYWORDS: Lock-Up Devices, Fluid Viscous Dampers, Limited Displacement Damper 1. INTRODUCTION Along with the rapid economic development in China over the past two decades, a large number of highways and bridges have been built in China. By 2004 China constructed 1.81 millions kilometers of roads and 30 thousand kilometers of highways.

China's Major Bridges Summary 1. Background
China’s Major Bridges Maorun FENG Maorun Feng, born in 1942, graduated from the Tangshan Professor Railway Institute with a Master’s Chairman of Technical degree, has been engaged in the Consultative Committee, design and research of bridges for 40 Ministry of years. He is the Chairman of Technical Consultative Committee Communications and the Former Chief Engineer of the Beijing, China State Ministry of Communications. He is also the current Chairman of China Association of Highway and Waterway Engineering Consultants. [email protected] . Summary In response to continuous economic development over the past 30 years, China has mobilized a program of large scale bridge construction. The technology of various types of bridges, including girder bridges, arch bridges, and cable-supported bridges, has been developed rapidly. Bridge spanning capacity has been continuously improved. Girder bridges with main span of 330 m, arch bridges with main span of 550 m, cable-stayed bridges with main span of 1088 m and suspension bridges with main span of 1650 m have already been built. Moreover, two sea-crossing bridges with overall length over 30 km have also been opened to traffic. This paper briefly introduces China’s major bridges, including girder bridges with spans greater than 200 m, arch bridges with spans greater than 400 m, cable-stayed bridges with spans greater than 600 m, and suspension bridges with spans greater than 1200 m. These bridges represent technological progress in such aspects as structural system, materials, as well as construction methods and equipment. Key words: girder bridge, arch bridge, cable-supported bridge, cable-stayed bridge, suspension bridge, steel-concrete composite bridge 1.
