1苏通大桥主桥结构体系研究显示文摘苏通大桥主跨1 088 m,是目前世界上最大跨径的斜拉桥。大桥桥位处建设条件复杂,抗震和抗风要求高,选择合理的桥梁结构体系是保证结构安全和功能的关键。介绍了苏通大桥结构体系的比选过程,比较了全飘浮、黏滞阻尼器、液压缓冲器和塔梁固接4种体系,重点分析对比了不同参数下黏滞阻尼器和液压缓冲器的结构响应,首次提出了用于桥梁的带有附加限位功能的特大型液体黏滞阻尼器,对阻尼器的设计参数进行了分析研究,并在苏通大桥上实现了这一新型装置。张喜刚 裴岷山 袁洪 徐利平 朱斌 2009中国工程科学2009,11,3:13
2General design of Sutong Bridge显示文摘The main span of Sutong Bridge is a double-pylon,double-plane cable-stayed bridge with steel box girder,which has the world's longest central span of 1 088 m within cable-stayed bridges.To overcome problems caused by severe meteorological conditions,perplexing hydrological conditions,deep buried bedrock and higher navigation level,many new technics and methods were created.Keys including structural system,steel box girder,stayed cable,tower,pier,tower foundation,collision avoidance system,wind-resistance,seismic-resistance,structural nonlinear response and structural static stability were presented individually in this paper.Zhang Xigang Yuan Hong Pei Minshan Dai Jie Xu Lin 2009Engineering Sciences2009,7,1:4
3Study on structural system of Sutong Bridge显示文摘Sutong Bridge,whose layout is [(100+100+300)+1 088 +(300+100+100)] m,marks the largest span of cable-stayed bridges in the world.The complex natural condition at the bridge site and the strict requirements for resistance of wind and seismic action make it crucial to choose a favorable structural system to assure the function and safety of the bridge.The comparison among several optional structural systems for Sutong Bridge is illustrated.After detailed analysis is carried out for viscous damper and hydraulic buffer,super liquid viscous damper with additional displacement limitation is designed for the first application in bridge engineering.The parameters for the damper is analyzed and studied and the dampers are installed successfully after quality tests.Zhang Xigang Pei Minshan Yuan Hong Xu Liping Zhu Bin 2009Engineering Sciences2009,7,1:0
4Key technology and innovation of Sutong Bridge显示文摘Sutong Bridge is a cable-stayed bridge across Yangtze River with the main span of 1 088 m. This article outlines technical challenges,key technology and innovation in the design and construction such as scour protection,lowering steel cofferdam,construction platform establishment,construction and control of pylons,fabrication and damping of long cables,erection and control of steel box girders.Zhang Xiongwen 2010Engineering Sciences2010,8,2:0
