摘要
以南京地铁某明挖车站深基坑为工程背景,利用大型通用有限元软件,对深基坑支护结构变形进行了2维有限元分析计算,并将计算结果同现场实测数据进行了对比分析,验证了2维有限元计算方法在长条形地铁深基坑中的的实用性,为今后的基坑工程计算提供参考。
Taking a deep open excavation of Nanjing subway station as the engineering background,the deformation of the support structure of the excavation was studied using the common finite element software in two-dimensional. The analysis was compared with the spot inspections. The results shown that the two-dimensional finite element method was suitable for the strip subway excavation and could provide some references to the future deep excavation design.
