Abstract

In this paper, a fuzzy information granulation method combined with a support vector machine time series prediction model(FIG-SVM) is established for a subway cross passage project of Ningbo Metro Line 3. The FIG-SVM prediction model was used to predict the ground settlement of the subway access during the shield construction process. It was found that the FIG-SVM prediction model can effectively predict the ground settlement trend for the next construction stage based on the historical data of the ground settlement.
