摘　　要：由于工后沉降对软土地基影响较大,为此正确估算沉降量意义重大。总结目前适用于软土地基的沉降预测方法,结合工程实践,对沉降预测方法进行验算,以比选出适用于宁波地区的沉降预测方法。研究表明,对于宁波地区的软土地基,三点修正指数曲线法具有很好的适用性,沉降预测效果较好。It is important to accurately predict the settlement of soil improvement projects since it has a large impact on the soils after the construction.This paper first summarizes the settlement prediction methods that are used in the soft soils,and then the settlement prediction methods are used in a project to predict the settlement so that the methods that are most applicable to soft soils in Ningbo area can be selected.The results indicate that the modified three-point parabolic curve method proposed by Chen has a better prediction the settlement of soils in Ningbo area.

关 键 词：软土地基 沉降 三点修正指数法 堆载预压
