Displacement Predicton of Underground Stabilisation Engineering

According to the nonlinear characteristics of displacement time series of underground stabilization engineering,and based on phase space reconstruction theory and the powerful nonlinear mapping ability of support vector machines,the information offered by the time series datum sets can be fully exploited and the trend of displacement evolution of underground stabilization can be precisely predicted by making real-time predicting.The experimental results suggest that the methods based on phase space reconstruction and v-SVR algorithm are very accurate,and the study can help to build the displacement forecast system to analyze the stability of underground engineering.
