Application of QPSO-LSSVM in tunnel surrounding rocks deformation prediction
Predicting and analyzing tunnel surrounding rocks deformation is of great significance to the safe implementation of tunneling projects. In this paper, the QPSO-LSSVM algorithm is applied to the study of tunnel surrounding rocks deformation prediction, and case study and validation are conducted based on indicator-based data and time-series data. The results show that the QPSO-LSSVM algorithm outperforms the PSO-LSSVM as well as the LSSVM algorithm in the case analysis of indicator-based data, while the QPSO-LSSVM algorithm outperforms the seven methods of GM(l,l), ARIMA(l,l,l), BP neural network (BP), linear regression (LR), SVR, LSSVM, and PSO-LSSVM in the analysis of time-series data. Therefore, applying the QPSO-LSSVM algorithm to the tunnel surrounding rocks deformation prediction analysis is feasible and efficient. This provides new ideas for machine learning in the field of tunnel surrounding rocks deformation prediction.
