摘要
水泥土桩复合土钉支护体系作为一种新的支护形式在基坑工程中的应用越来越多,而在整体稳定性计算过程中如何考虑水泥土桩的作用尚有争议。通过两种规范对复合土钉稳定性分析方法的对比,分别采用两种计算方法,对不同土质条件下复合土钉中的水泥土桩进行稳定性计算,得出水泥土桩在复合土钉支护结构稳定性中的重要作用,在设计中应适当考虑水泥土桩的作用。
The composite soil nailing system with cement-soil piles as a new supporting form is widely used in the foundation pit engineering,and in the overall stability calculation how to consider the role of cement-soil piles is controversial. Through two kinds of specifications in the stability analysis methods for composite soil nailing,two kinds of calculation methods are used in the composite soil nail stability calculation under different soil conditions,and the important effect of cement-soil piles in the composite soil nailing structure stability is obtained,which should be appropriately considered in the design.
