繁华地段穿越运营地铁车站基坑开挖施工技术

Construction technology of foundation pit excavation crossing subway station in operation at a busy downtown street

以长沙地铁3号线火车站穿越正在运营的地铁2号线车站工程为依托,在充分调研地质资料和周围环境的情况下,确定了"分区、分步、分层"的基坑开挖思路,并阐述了施工中的关键技术及工艺流程,提出了施工要求和安全措施,为该工程的安全、顺利完工创造了良好的条件。

Taking the engineering of Changsha metro line 3 train station through the operation of metro line 2 station,in the case of full geological data research and detailed analysis of the surrounding environment,this project determines the＂partition,step by step,stratification＂of the overall idea by widely solicit expert opinion. In order to create a good condition for the safety and smooth completion of the project,the key technology and process flow are deeply studied and demonstrated,the construction technical requirements and the safety measures are put forward.
