Application research on high speed railway roadbed deformation monitoring based on EM processing

By establishing a mathematical model based measured data, it is possible to predict the post-construction settlement data of the high-speed railway subgrade accurately, which can provide an effective reference for the timing of laying. The EM processing is used to establish a mathematical model for the measured settlement data, and the appropriate initial parameters are selected to predict the post-construction settlement data. The modeling results show that the EM processing has good accuracy and reliability in predicting the post-construction settlement of the high-speed railway subgrade.
