摘要
目前上海市域铁路缺少具体规范指导设计,对市域铁路桥梁主要技术标准如:列车设计活载、桥梁结构形式、桥墩结构形式、抗震分析、桥墩纵向水平线刚度、竖向自振频率、结构变形等进行分析,可为今后市域铁路桥梁设计提供参考。
At present,there is no detail norm to guide the design of the city railway in Shanghai.This paper analyzes the main technical standards of city railway bridges,i.e.the design live load of train,structural type of bridge,structural type of bridge pier,anti-seismic analysis,longitudinally horizontal line rigidity of bridge pier,vertical natural vibration frequency and structure deformation,which can be referred for the design of city railway bridges in the future.
