北京地区暗挖地铁车站结构设计方法研究进展综述

A review of the research progress on structural design methods of shallow buried underground subway stations in Beijing

由于受城市特点、道路交通状况以及地下市政管线和各种构筑物影响,北京地铁车站采用浅埋暗挖法施工占有重要的比重。结合近年来参与的暗挖地铁车站结构方案研究成果,以地铁车站结构风险及周边环境风险控制为设计方案制定的依据,阐述了在“暗挖车站拱部竖向地层压力计算方法、地层沉降控制标准、地层加固设计、初期支护承载作用以及结构关键工况”等方面的研究进展。

Due to the influence of urban characteristics,road traffic conditions,municipal pipelines and various buildings,the construction of metro station with shallow excavation method occupies an important proportion.Combined with the research results of the design of the metro station structure scheme in recent years,based on the risk control of subway station structure and surrounding environment,this paper introduced the research progress in calculation method of vertical soil pressure at the arch of metro station,control standard of surface subsidence,design of soil reinforcement,bearing capacity of initial support and key working conditions of structure etc.
