Abstract:

To accurately estimate the rock mass properties of a high-speed railway tunnel, a back-analysis method using multiple monitoring data based on the least-squares support vector regression(LS-SVR)algorithm is presented. The root mean square error(RMSE)and mean absolute percentage error(MAPE)are used as evaluation indices. The results of the parameter estimation are compared with those of the back propagation neural network(BPNN)and Gaussian process regression(GPR). The results show that for the single type of monitoring data, the LS-SVR model with vault settlement has the lowest RMSE and MAPE values. Moreover, as the data type increases, the RMSE value of the LS-SVR decreases, especially for the model with the mixed data of vault settlement, convergence, and floor heave. The comparison results show that the presented model has lower RMSE and MAPE values than BPNN and GPR. The LS-SVR model using multiple monitoring data shows better performance than existing back-analysis methods, improving the accuracy of the estimation of rock mass properties.
