摘要
土钉墙支护结构一般在深度小于5m的基坑工程中的应用较为普遍。本工程考虑到土质条件、基坑周边工况及变形要求等实际情况将土钉墙结构用于深基坑中。本文介绍了南通某深基坑采用土钉墙支护结构的设计思路与依据,阐述了支护结构的设计计算,确定了本工程条件下最优的设计参数。最后,根据实际基坑监测的位移数据进行了变形分析,所得位移数据均满足设计及规范要求。结果表明该工程支护结构满足安全稳定性要求,具有安全、经济、合理的优点,同时为类似工程设计参数的选取提供了实践依据。
The support structure of soil nailing wall are applied widely in foundation pit which is less than 5 m depth.In consideration of the soil condition and peripheral environment condition and deformation,the support structure of soil nailing wall was applied in this project in Nantong.In this paper,the designing thoughts and bases why the support structure of soil nailing wall was chosen was introduced.This paper was focuses on the design and calculation of the support structure.And the displacement data of this foundation pit monitoring was analyzed in this paper.The experimental result indicated that the support structure was safe and stable,and this support structure has the advantages of safety,economy and rationality.This project can be used as a successful case to popularize and apply in Nantong.
