摘要

从影响基坑周围土体沉降的诸多因素中选出3个主要因素：弹性模量、降水深度和渗透系数，利用二维有限元法分析了它们对基坑周围土体沉降性状的影响。同时通过建立二维有限元模型，研究了工程上采用的回灌和止水措施对减小地表变形的作用。研究表明，使用回灌井、回灌沟或止水帷幕措施可减小地表总沉降和不均匀沉降。

Abstract

From many influence factors which affected the deformation of foundation pit’s surrounding soils

three main effective factors such as Young’s modulus

dewatering depth and the permeability coefficient had been chosen as the significantly important factors for input in the 2-D FEA model and the behaviors of settlement were then analyzed. Furthermore

by the 2-D FEA model

the effect of the reduction of the surface settlement due to different distances of recharge or the depth of water-sealing was studied. The obtained results verified that the surface settlement and surface differential settlement of the ground surface could be largely reduced by recharging or water-sealing.
