| Abstract: | The work principle and the modified technology of BP neural network are studied,and the factors influencing surrounding rock stability in tunnel are analyzed.A neural network model for predicting surrounding rock stability classification is built based on the modified MBP neural network. The applied research at mine show that the model has sound performance and high precision,with the prediction results for predicting well in accordance with engineering practice.The feasibility and practicability of the model is thus verified. |
