抗隆起稳定性验算是软土地区基坑围护设计的一项重要内容,它通常是围护结构嵌固深度的控制因素.主要针对新行标《建筑基坑支护技术规程(JGJ120-2012)》在软土地区地铁等窄条形基坑应用过程中,出现的围护结构嵌入比过大问题进行研究,并通过选用工程实例进行计算分析,以期对类似工程提供一定借鉴作用.
抗隆起穩定性驗算是軟土地區基坑圍護設計的一項重要內容,它通常是圍護結構嵌固深度的控製因素.主要針對新行標《建築基坑支護技術規程(JGJ120-2012)》在軟土地區地鐵等窄條形基坑應用過程中,齣現的圍護結構嵌入比過大問題進行研究,併通過選用工程實例進行計算分析,以期對類似工程提供一定藉鑒作用.

The calculation of resistance to uplift stability is an im-portant content in the design of foundation pit in soft soil area. It always controls the embedded depth of enclosing structure. The re-search mainly aims at the embed ratio of the enclosing structure oversize under usage of the new industry standard–The Architec-ture Foundation Pit Supporting Technical Specification in the sub-way narrow strip foundation pit in soft soil layer, and calculated and analyzed by choosing a project instance, in order to provide certain reference for similar engineering.
