深基坑支护工程,采用何种支护方案,除根据基坑开挖深度设计外,还要根据场地地质地貌及地层物理力学性质进行支护结构验算。深基坑支护目前国内外方法很多,而且尚在不断发展之中,每一种支护方法都有各自的适用范围和一定的局限性。对于一个具体的深基坑支护工程,究竟采取什么样的支护方案,要做具体分析。本文主要根据实例分析了深基坑支护工程中深层搅拌桩墙施工技术。
In addition to the design of the excavation depth, the support structure of the deep foundation pit supporting project should be checked according to the geology and geology of the site and the physical and mechanical properties of the formation. Deep foundation pit support at home and abroad a lot of ways, and is still under continuous development, each support method has its own scope of application and some limitations. For a specific deep foundation pit support project, what kind of support program to take, to do a specific analysis. This article mainly analyzes the construction technology of deep mixing pile wall in deep foundation pit supporting project according to the example.
