Research and Practice on New Structural System of Super Long Span Cable-supported Bridge
Taking Changtai Yangtze River Bridge and Zhangjinggao Yangtze River Bridge under construction as examples,this paper analyzes the structural system of super long span cable-stayed bridge and suspension Bridge.Firstly,the key technical problems in structural system design,such as the restraint of pylon and girder,anchorage of SOTTA and caisson foundation of super long span cable-stayed bridge,the tower restraint,tower form,anchor foundation and orthotropic deck plate of super long span suspension bridge were researched.Then,new structure systems for super-long span bridges is proposed as a solution.It is expected to provide reference for the construction of other super-long span cable-supported bridges in China.
