Abstract: According to the analysis of the construction of roadbed settlement,this paper predict the roadbed settlement with grey linear regression model and Verhulst grey model.The settlement data belongs to the S type series,the two models are tested using programming with MATLAB language in MATLAB 9.0platform.The results show that the Verhulst grey model is more suitable for S sequence data and can better respond to the settlement trend,consistent with the distribution characteristics of S sequence analysis,and higher forecast accuracy.It can provide effective information for monitoring of settlement.
