地下连续墙在超深基坑支护中的应用分析

The Analysis of Underground Continuous Wall Applied in Deep Excavation Supporting

地下连续墙由于刚度大、变形小、整体性好,且可以和地下室外墙合二为一,在超深基坑支护中被广泛应用。以南益广场超大深基坑为例,该基坑工程采用地下连续墙结合内支撑的支护形式,通过监测数据分析,显示基坑的变形均在预警范围,是地下连续墙在超深基坑支护的一次成功应用。

Due to the big rigidity, small deformation,good integrity and two walls can be combined into one,under- ground continuous wall is widely used in deep excavation supporting.The article takes the large deep excavation of Nanyi Square as an example,the deep foundation pit uses underground continuous wall combined with internal support,and the monitoring data shows that the deformation of the foundation pit is no more than warning scope, which shows that it is a successful application in deep excavation.
