深基坑工程复合土钉墙支护设计与施工

Design and Construction of Composite Soil Nailing Wall in Deep Foundation Pit Engineering

通过工程实例介绍水泥搅拌桩在深基坑支护中无法达到设计深度且桩底高出基坑底面时采用复合土钉墙的设计与施工,指出设计中遇到的问题,阐述了设计原理和施工方法,可供类似工程参考。

If the cement mixing pile can not achieve the design deepth and the bottom of the pile higer than the bottom of foundation pit,the composite soil nailing wall is adopted as the supporting structure.Combined with a specific engineering example,the problem faced in the design is pointed,and the principle of design and construction method is explained in this paper,which can give reference to similarity engineering.
