摘　　要：介绍基坑开挖引起的土层水平位移和横向沉降空间效应,借助有限元软件,计算得到耦合主要影响因素的地表纵向沉降空间分布公式。并以此为基础确定基坑开挖环境影响分区,分析了既有建筑物处于不同分区时的受影响模式和影响度。This paper introduced horizontal ground displacement and the space effect of the lateral settlement caused by foundation excavation. The spatial distribution formula of longitudinal settlement which coupled main factors was obtained based on the finite element software. And on this basis, the impact partition of environmental caused by foundation pit excavation was conducted as well as the mode and degree of influence on the existing buildings in different partitions were analyzed.
