Study on Deformation Prediction of the Tunnel Surrounding Rocks Based on Non-Equal Time-Interval Grey Model

Abstract:

The thesis develops an non-equal time-interval GM (1, 1) model to forecast the deformation of the tunnel surrounding rock. A program is compiled via MATLAB 7.1 platform to implement the model. With the assistance of the program and the monitoring record of the convergence, the deformation is predicted and the error is analyzed. The numerical results indicate that the non-equal time-interval GM (1, 1) model does well in predicting the deformation of tunnel surrounding rock and is worthy to put into use in tunnel engineering.
