摘　　要：首先在对现有的五种深基坑周围土体沉降计算方法分析的基础上提出了一种新的沉降计算方法,即分段函数法。其次采用分段函数法和现有的五种典型沉降计算方法分别对上海、天津等两个工程实例进行计算,并将计算结果与实测地表沉降值进行比较分析,结果表明本文提出分段函数法是可以接受的。A new soil settlement calculation method,namely piecewise function calculation method,which brings convenience in calculation and has higher accuracy for the settlement forecast in section of larger settlement has been proposed in this paper through analysis of previous five methods. This method as well as five previous methods was applied in two projects in Shanghai and Tianjin and the results were compared with measured settlement values,which verify the effectiveness and practicality of the proposed sub-function calculation method.
