| Abstract: | In order to ensure the safety of metro operation,this paper proposes a prediction method of surface settlement in metro tunnel construction based on finite element and gray analysis.This method uses the MADIS-GIS finite element analysis software to build a three-dimensional finite element model of the tunnel.Combined with the gray GM(1,1)model,it forecasts the surface settlement in the tunnel construction,and divides the accuracy grades,so as to obtain highprecision prediction results.The analysis results show that this method effectively predicts the surface settlement of metro tunnel construction,and provides guarantee for metro tunnel construction and metro operational safety. |
