综合支护技术在软土深基坑支护工程中的应用

On application of comprehensive support technique in support projects of soft-soil deep foundation pit

针对深圳市图书馆大厦深基坑支护工程中采用搅拌桩截水帷幕联合土钉墙及预应力锚索的综合支护方法进行了介绍,指出采用该方法使得基坑施工工期大大缩短,成本降低,且经现场结果测试,边坡没有发生明显位移,基坑内也没有出现渗水现象,值得推广。

The paper indicates the mixing pile water-interception curtain combined soil nailing walls and the comprehensive support methods in the prestressed anchor cable are adopted in the deep foundation pit support projects in Library Mansion of Shenzhen,indicates the adoption of the method can shorten the engineering period greatly,lowers the costs,no obvious displacement at slopes,nor the leakage in the foundation pits by the field measurement,so it can be further extended.
