摘　　要：结合北京市通州运河ONE项目基坑地下连续墙工程,介绍了北京地区复杂环境下深基坑地下连续墙施工的主要技术措施,地下连续墙施工过程中导墙施工、泥浆制作、成槽、钢筋笼制作、混凝土浇筑中的施工要点及注意事项,解决了一系列的重点、难点问题,形成了一套系统而完善的地下连续墙施工技术。探讨了周边和地下复杂环境下工程施工中,可能出现的各种问题及相应预防控制措施,研究的规模、深度、涉及的问题均较以往有很大的发展。本工程为复杂条件下深大基坑地连墙支护施工,提供了参考。Combined with the deep excavation and diaphragm wall construction of Tongzhou Canal ONE Project,some primary key technique measures for diaphragm wall construction of deep excavation were introduced,as well as construction points of guide wall construction,mud making,excavating,reinforcing cage making and concrete pouring.Then a series of key problems and difficulties are solved to form a set of excellent diaphragm construction technology.The paper also discusses certain problems and relative preventive action under the complex environment,and improves greatly in scale,depth and problems involved.The successful implementation of the project can provide guidelines for construction of deep excavation and diaphragm wall construction in domestic engineering practice.
