摘　　要：在采用地下连续墙作为围护结构的基坑研究方面,目前主要研究方向为基坑开挖过程中的变形控制及地下连续墙施工过程中槽壁稳定性控制,对地下连续墙施工过程所造成的环境变形研究较少。依托惠民大道综合改造工程项目,以槽壁加固、地面超载、泥浆比重为变量采用ABAQUS软件对地下连续墙成槽过程中土体变形进行分析,并根据计算结果制订对应的成槽控制措施。The main research directions of foundation pit using diaphragm wall as retaining structure are deformation control during excavation and stability control of bulkhead during diaphragm wall construction,the research of environmental changes is rare.Based on Huiming avenue reconstruction project,this thesis uses ABAQUS to analyze the soil deformation in the process of diaphragm wall construction by counting bulkhead enforcement,the ground overload and the proportion of mud as variables,and formulates the corresponding control measures according to the calculation results.
