新建淮扬镇铁路长江桥位线路方案研究

摘要

新建淮扬镇铁路扬州至镇江段按速度250km/h城际铁路标准设计。该区段线路基本走向主要受跨越长江特大桥桥位控制。通过对长江特大桥建桥条件及引入扬州、镇江地区条件进行全面系统比较和综合分析，提出五峰山长江桥位方案。%Yangzhou-ZhenjiangsectionofthenewlybuiltHuaian-Zhenjianrailwayisdesignedastheintercityrailway withthespeedof250km/h.ThebasicalignmentofthissectionismainlyaffectedbythesupermajorYangtzeRiver bridgesite.BymeansofcontrastiveanalysistotheconstructionconditionofYangtzeRiversupermajorbridgeandcondi-tionsledintoYangzhouandZhenjiangregion,thebridgesiteschemeofWufengshanYangtzeRiverbridgeisputfor-ward.
