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。

Abstract: 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.
