浅谈某地铁明挖车站基坑土方开挖

Discussion on the foundation pit excavation of a subway open cut station

以某地铁车站基坑工程为例,详细介绍了采用明挖顺作法进行基坑土方开挖的施工方案及工序,阐述了基坑土方开挖与支撑及桩间喷射混凝土施工的技术措施,从而确保基坑周边土体变形在设计允许值内,以实现安全施工。

With some subway station foundation pit engineering as example,the construction planning and procedure of foundation pit excavation with open cut method were detail introduced.The technical measures of foundation pit excavation and supporting,inter-pile shot concrete construction,therefore guaranteed foundation around soil body deformation was in the designed value scope,so as to realize safe construction.
