Gray Correlative Analysis in Long-term Settlement of Metro Shield Tunnel
摘要
Abstract
Metro shield tunnel in soft soil area will have a certain long-term settlement during operation .The excessive long-term settlement will have a negative impact on the normal operation and safe use of the subway .In order to analyze and solve the problem of metro train operation safety caused by long-term settlement , it is very important to predict the long-term settlement of shield tunnel ac-curately.Based on the measured data of Suzhou Metro Line 1, 4 adjacent tunnel settlement monitoring points are selected in this pa-per.With the help of Matlab , grey correlative model and grey model are established respectively to forecast and analyze the long -term settlement of Suzhou Metro Line 1.The results show that the average fitting precision of gray correlative model is 0.44, which is more precise than gray model .And its predicted results are more close to the measured values of the settlement .Due to its advantages of good integrity , gray correlative model can be used to predict the long-term settlement of shield tunnel .This article aims to provide im-portant reference for further studying the long-term settlement of metro shield tunnel in Suzhou and other regions .关键词
