Analysis on Settlement Feature of Soft Soil Subgrade and Application of the MMF Model

A large number of observational data and theoretical studies indicate that the development law of soft soil subgrade settlement curve generally goes from occurrence, development, stable, and then to a certain limitation. Its manifestation is in line with the basic form of growth curve. This paper analyzed the engineering and settlement characteristics of soft soil subgrade to establish the MMF model for prediction in whole course of soft soil subgrade settlement ; and Origin software is used to solve the parameters of the model and give the way in which the model is solved; in addition, the effect of model prediction is discussed. The prediction result via case study shows that the model established has the scientificity and applicability.
