摘要
北京地铁14号线京顺路站A出入口明挖基坑施工中,针对地面及地下的复杂环境,采用倒挂井壁法施工。通过分期开挖、临时支撑+换撑的方法保证了施工关键工期的节点及施工安全。
Considering the complex ground and underground conditions,inverted shaft wall construction method was adopted in the open-excavation foundation pit project of Beijing subway line 14 Jingshun Road Station entrance A.Staged excavation and temporary support plus support replacement were adopted to guarantee the construction schedule nodes and construction safety.
