摘　　要：为了保证高速铁路结构和行车安全,需要对下穿高速铁路桥梁U型槽的大体积基坑开挖方案进行严格计算控制和合理施工组织设计。以某市政路采用U型槽下穿某高速铁路桥梁的大体积基坑开挖过程为例,分析了其对高速铁路桥梁的响应,对该大体积基坑开挖方案进行优化研究,可为同类工程提供参考。In order to ensure the structure and traffic safety of high-speed railway,it is necessary to carry out strict calculation control and reasonable construction organization design of the excavation scheme for the mass foundation pit of U-grooveunder-crossing the highspeed railway bridge.Taking the excavation process of mass foundation pit of U-groove under-crossing a high-speed railway bridge over a municipal road as an example,the response to the high-speed railway bridge is analyzed,the optimum research on the excavation scheme for the mass foundation pit is made,so as to provide reference for similar projects.
