王胡砦地铁车站基坑开挖施工工艺

Construction Technology of Foundation Pit Excavation at Wanghuzhai Metro Station

我国地铁车站基坑开挖大部分采用明挖施工法,且基坑埋深都很大,因此,对其施工质量提出了更高的要求。基于此,论文以王胡砦地铁车站为例,分别从基坑降水、开挖和监测3个方面对地铁车站基坑开挖施工工艺进行研究,并提出保证基坑安全稳定的措施。

Most of the foundation pit excavation of subway stations in China adopts open-cut construction method,and the depth of the foundation pit is very large,which puts forward higher requirements on the construction quality.Based on this,the paper takes Wanghuzhai Subway Station as an example to study the excavation technology of subway station from three aspects:dewatering,excavation and monitoring,and puts forward the measures to ensure the safety and stability offoundation pit.
