摘要
在道路与管道穿越铁路工程中,工作坑支护的安全设计对确保铁路行车安全具有重要影响。文章结合工程实例研究了基坑支护型式的优化选择,为今后类似项目的设计与管理工作提供参考。
In the underpass projects,the safety design of working-pit supporting structure has an important influence on making railway operation safe.This paper studies optimization selection for supporting structures of underpass working-pit according to an actual case,gives reference to similar projects on design and management in the future.
