摘要： 地下连续墙工法的广泛应用使得深基坑技术日益成熟，特别是在地质条件恶劣区域。以复杂地层情况下地下连续墙施工实例为背景，介绍地下连续墙施工过程中难点及注意事项。同时，在基坑开挖阶段对地下连续墙实时监测，对监测数据进行适当地处理，反映地下连续墙变形的实际情况。结合地下连续墙变形监测数据，表明该工法的应用效果良好，期望能对类似工程有一定的参考。

Abstract: The application of underground slurry wall in the deep excavation projects results in a better performance of excavation supporting system, especially, for deep excavations under the complicated subsurface conditions. In the practical applications, the slurry wall construction technique should allow slight modifications in order to fit for the specific subsurface conditions. The key as well as most difficult aspects of the slurry construction methods are introduced in this paper through a case history. The construction monitoring should be performed and the monitoring data should be processed so that the deformation of the slurry wall can be presented. The construction monitored data indicate that the application of slurry wall method in the deep excavation support is a success.
