摘要

在深厚淤泥质软土中采用钻孔灌注桩加旋喷锚索作为围护结构，辅以水泥土搅拌桩加固被动区，如果施工过程控制不当，基坑容易产生较大变形。文章以武汉市东西湖区某基坑工程为例，运用数值模拟方法模拟基坑塌方过程，尝试分析该基坑产生过大变形的原因，并对类似基坑工程提出建议，具有一定的借鉴和指导意义。

Abstract

In deep silty soft soil

bored piles combined with jet-grouted anchor cables are used as the retaining structure

supplemented by cement-soil mixing piles for passive zone reinforcement. If the construction process is not properly controlled

the foundation pit is prone to significant deformation. Taking a case study from a certain foundation pit project in Dongxihu District

Wuhan

this article uses numerical simulation to simulate the collapse process of foundation pit

attempts to analyze the reasons for excessive deformation of this foundation pit

and puts forward suggestions for similar foundation pit projects

which has certain reference and guiding significance.
