| 英文摘要 | This study utilizes the support vector regression (SVR) model to predict the tunnel crown displacement (TCD) induced by the blasting excavation. 95 blasting operations considering the tunnel shape parameters, the blasting parameters, the explosive parameters, and the rock mass properties are used to train and test models. To enhance the model prediction performance, a novel combination of the arithmetic optimization algorithm (AOA) with the chaos mapping (CM) called CMAOA, is proposed to select the optimal hyperparameters of the SVR model with advantages of the computing speed and the optimization ability. Sixteen benchmark functions are adopted to verify the authenticity of the prediction performance improvement of the CMAOA, and six statistical indices are used to evaluate the performance of the proposed hybrid models for predicting the TCD. The evaluation results show that the SVR optimized by the AOA with Circle map (CirAOA-SVR) model has the best prediction accuracy among all models. The results of parameter analysis indicate that the degree of bonding of bedding surface is the most important input parameter for predicting the TCD, but the blasting and explosive parameters with fine importance scores cannot be ignored either.
