超大跨度铁路桥梁列车加载长度研究
Research on Train loading Length on Super-long Span Railway Bridge
摘要
Abstract
The loading length on super-long span railway bridge plays an important role in determining the cross section and cost of super-long span bridges and it is necessary to analyze the train loading length for bridges of over 1km long. The research aims to find out a suitable loading mode for super-long span bridges under medium-live load and ZK load. The research concludes that the Intercity and passenger dedicated railway lines may use 450 meters loading length. The loading length for railway lines of mixed passenger and freight and freight dedicated railway lines may be determined based on the formation of the freight train, and the effective length of railway station may be taken as the super-long bridge’s loading length. For bridges with the main bridge less than 3km, only one loading length is added.关键词
