分坑技术在饱和软黏土深大基坑变形控制中的应用
摘要:以紧贴苏州某地铁车站的深大基坑为例,依据时空效应原理,利用分坑技术控制深大基坑引起的变形,从而确保紧贴地铁车站的安全。通过对基坑周边环境实测数据采集、整理及分析证明,采用合理的分坑施工技术,可解决饱和软黏土地区深大基坑开挖变形控制难题,达到控制基坑变形并保护周边环境的目的。
Abstract:Taking the deep and large foundation pit adjacent to a subway station in Suzhou as an example, the deformation caused by the deep and large foundation pit is controlled by using the principle of time and space effect and the pit dividing technology, and the safety of the close subway station has been guaranteed. The measured data of the surrounding environment are collected and analyzed. In the saturated soft clay area, based on reasonable pit division construction technology, the deformation of deep and large foundation pit during excavation could be controlled and the surrounding environment could be protected.
