摘　　要：以某深基坑支护工程为研究背景,采用有限元MIDAS分析软件对深基坑开挖地表沉降随深度变化的影响进行了数值模拟,并将数值模拟计算结果与设计计算值对比,分析表明:地表沉降随深度变化大致呈抛物线分布,最大值出现在距坑边约8 m处,与设计计算相一致。On the basis of a building project of deep foundationpit supporting engineering, Using finite element analysis softwareof MIDAS deposition was simulated with the depth of excavationon deep foundation pit surface, the result of Numerical simulationcompared with the value of design, The analysis showsthat： The surface subsidence is approximately parabola distributionchanges with depth, the maximum value in the distance ofthe pit at about 8m , consistent with the design calculation.
