［提要］随着城市建设的完善，城市中心基坑开挖时需要保护的设施越来越多，基坑开挖变形控制要求也越来越高。因此，也需进行研究和控制围护结构施工对周边环境的微变形影响。结合周边环境变形实测数据、数值分析、工程实践，研究了在基坑支护中应用较多的地下连续墙成槽对周边环境的影响特点及控制措施，可为实际工程当中控制地墙施工对周边环境的变形影响提供理论和技术支持。

Abstract: With the improvement of the urban construction, foundation pit excavation in the heart of the city face more and more protection facilities, and deformation control is becoming stricter. Therefore, the influence of retaining wall construction on the surrounding environment is also needed to study and control. Based on the measured deformation, numerical analysis and engineering practice, the deformation on the surrounding environment and control measures of diaphragm wall construction is studied. The analysis result can provide theoretical and technical support for control deformation of diaphragm wall construction in projects.
