详细信息

摘要: 以上海地区某超深基坑工程为背景，介绍了基坑围护设计中支撑后拆法的应用。对设计及施工中存在的难点进行了分析，并针对性的给出处理、解决方案。对比分析了数值模拟、理论计算结果与工程实测数据，结果较为接近，监测数据无超过报警值情况发生，基坑开挖对周边环境的影响满足规范要求。采用支撑后拆法的基坑围护设计在本基坑工程实践中取得了良好的实施效果，值得在同类工程设计、施工中借鉴和参考。

Abstract: For a super-deep excavation in Shanghai, the application of late-dismantling support in the design of retaining structures is introduced. The difficulties of the design and construction are analyzed, and the relevant solutions are given. A comparison among numerical simulations, theoretical results and engineering data shows that the results are close, and the monitoring data do not exceed the warning values. The influences of pit excavation on the surrounding environment can meet the requirements of specification. The design method is successfully used in this project and achieves satisfactory effects. It will provide some reference for the design and construction of similar projects.
