排桩和土钉墙围护结构在某基坑支护工程中的应用

Application of Soldier Pile and Soil Nailed Wall System in a Deep Excavation Project

基坑支护工程是一个风险性工程,不确定影响因素很多,必须采取有效的支护措施。现阶段,排桩和土钉墙是基坑支护工程中常用的支护形式,以某基坑支护工程为依托,介绍了该工程中排桩和土钉墙围护结构的应用,对不同区段分别采用排桩和土钉墙的支护设计进行了分析,实践表明采用该支护形式具有很好的效果,可在类似工程中推广应用。

Deep excavation projects are usually involve many uncertainties. It is therefore requiring effective and safe supporting system. Currently, soldier pile and soil nailed wall are commonly used as the deep excavation supporting system. This paper presents a case history of a deep excavation project using the combination of soldier pile and soil nailed wall as the supporting system. Different excavation areas were successfully supported by either soldier pile or soil nailed walls.
