深基坑开挖坑外地表沉降分析与计算

Analysis and calculation of ground settlement around foundation pit in deep excavation

通过对地表沉降曲线的两种不同假设 ,在分析地表沉降、基坑隆起、墙体侧移相互关系的基础上 ,推导了两个用来求算地表沉降量的估算式 ,经工程验证结果较满意。

From the two different hypotheses of ground settlement curve,this paper deduces two formulas which can estimate ground settlement based on analyzing the interrelation among pit upheaval,wall lateral movement and ground settlement.The result is satistfactory by verifying the formulas with cases.
