深基坑开挖引会影响甚至改变其临近地铁隧道的应力应变状态,对其相邻地铁隧道使用功能及地铁安全产生影响甚至造成严重危害。而逆作法可采取先支撑后开挖土体的方式进行施工,可最大限度的减少深基坑对相邻地铁安全的影响。本文通过邻近地铁的地下室逆作法施工案例的分析,结合逆作法的施工特点,对如何更好的保护地铁运营安全提出了相关措施和建议。
The deep foundation pit excavation will affect or even change the stress and strain of its adjacent subway tunnel, which may even cause serious damage to its subway function and subway safety. The reverse method can take the first support after excavation of soil construction methods can minimize the impact of deep foundation pit on the safety of the adjacent subway. In this paper, through the analysis of the construction cases of basement reverse construction near the subway and the construction characteristics of the reverse construction method, the paper puts forward the relevant measures and suggestions on how to better protect the subway operation safety.
