摘　　要：本文以采用"护坡桩+砼内支撑"方式实施基坑支护的小开挖面深基坑为研究对象,通过对该项目打桩开始至砼内支撑拆除整个全周期的基坑变形数据监测和分析,得出基坑及周边环境安全的结论.同时验证了砼内支撑方式对此类深基坑支护设计的有效性,为以后类似工程第三方开展监测工作提供经验和参考.In this paper,a deep foundation pit project supported by retaining pile and concrete internal support with small excavation area is studied.According to the monitoring and analysis of foundation pit deformation data in the whole process from the piling to the removal of concrete internal support,it is concluded that foundation pit and surrounding environment are safety.At the same time,the effectiveness of concrete internal support in such deep foundation pit support design is validated,which can provide experiences and references for the monitoring by the third part in similar projects.

关 键 词：护坡桩 砼内支撑 深基坑 监测数据 综合分析
