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.

Key words: Soft Soils, Settlement, ThreePoint Parabolic Curve Method, Surcharging Method
