摘　　要：苏州某小区大面积深基坑工程,周边环境复杂,施工条件有限。考虑基坑复杂性的特点及经济合理性,对比选取T SMW工法桩作为深基坑的主体围护结构,并采用钢筋混凝土''角撑+对撑"形式进行支撑支护。同时采用0650三轴深搅桩做止水帷幕,现已顺利施工,结果表明,此基坑支护结构设计及地下水控制措施是合理和有效的,设计方法可为类似工程提供参考。The deep excavation of a community in Suzhou is very deep,there is no more available space surrounding environment is very complex.Based on the surrounding complex environmental conditions of the site and economic rationality of the foundation pit,SMW method pile structure are taken to support the deep excavation with Reinforced concrete"comer brace+pair brace".At the same time,®650 three-axis deep mixing piles are taken to control the groundwater level of the inside and outside in the pit.The construction was successfully completed,and the results show that the design and groundwater control measures are reasonable and effective,and the design methods and monitoring data can provide a reference for other similar projects.
