摘要

在分析总结基坑周围地表沉陷变形计算方法的基础上，根据软土基坑变形规律，按指数曲线拟合基坑周围地表沉降变形，推导出在软土地区深基坑开挖中由支护结构变位引起周围地表沉降变形的计算方法，并通过实例分析、比较，预测地表沉降，对于周围环境要求严格的基坑工程提供了较可靠的计算方法，对于基坑周围环境保护有重要的意义。

Abstract

On the basis of analyzing and summarizing the method to calculate the ground surface settlement around the soft soil foundation pit and in the light of the deformation law of the soft soil foundation pit

the circumferencial ground surface settlement deformation of the pit is fitted in terms of exponential curves and the method is deduced to calculate the settlement deformation of the ccrcumferential ground surface of a deep foundation pit in soft soil regions that is caused by the deflection of the supporting system during excavation. Prediction is made for surface settlement through analysis and comparison of practical cases. A reliable method is put forword for the calculation of the settlement of the foundation pit projects having serious requirement on surrounding environments

which is of signifcance to enviromental protection.
