武汉市某基坑支护分析

Analysis of a Deep Excavation Site at Jiangan

介绍了武汉市江岸区某基坑的基本地质条件,通过对比分析武汉市常用的基坑支护方法,最终确定了采用水泥土重力式挡墙结合被动区加固的方法进行基坑支护,基坑设计计算满足了规范的要求。通过围护施工的组织设计,取得了经济适用、安全可靠等实际效果,得出了几点体会,对类似工程有借鉴作用。

This paper introduces the site geotechnical properties of a deep excavation project in Jiangan, Wuhan. Several common exca vation supporting methods were compared and the gravity retaining walls consisting of cement mixed soil columns with the reinforcement of passive zone are selected. The results indicate that the design meet the code requirements. The project shows that the selected meth od has advantages of cost effective and safe construction. The construction recommendations are proposed in the paper.
