摘　　要：本文针对软土地区超深地连墙施工中普遍关心的稳定性问题,首先对国内外地连墙开挖相关文献资料进行了综合分析。其次,依托上海机场联络线梅富路工作井基坑工程,采用三维数值方法对超深地连墙施工全过程土体变形特征进行了模拟分析,获得了超深地连墙动态施工过程的变形规律和扰动影响范围,并与实测数据进行了对比分析和验证,研究成果为超深地连墙工程的安全施工提供了参考。In this paper, aimed at general stability of ultra-deep diaphragm wall construction in soft area, firstly, literatures related to diaphragm wall around the world are summarized, then based on the Meifu road shaft of Shanghai airport connection line, comprehensive numerical simulation of the whole construction process of an ultra-deep diaphragm wall has been carried out. The results show that the characteristics of lateral displacement and disturbance range during ultra-deep diaphragm wall construction process, which are compared and verified by measured data. And the research results can provide reference for the safety construction of ultra-deep diaphragm.
