摘　　要：基坑开挖过程中如何保证自身施工安全及周围环境安全,并在设计期对基坑变形及地表沉降量进行估算,这是现在实际工程中迫切需要解决的问题。通过系统分析引起基坑周围土体变形的基本理论,研究基坑开挖引起地表沉降的计算原理,为计算实际工程地表沉降提供理论依据。How to ensure people＇ s own construction safety and environment safety during excavation process and, at the same time, how to estimate foundation deformation and surface settlement during design phase are the problems that need to be solved urgently in practical engineering. This article provides a theoretical basis for the calculation of the surface subsidence in the actual projects by analyzing the basic theories that cause pit soil deformation systematically and researching methods of calculating surface subsidence caused by excavation of foundation pit.
