| Abstract: | Introducing back propagation(BP) algorithm to wavelet neural network,and using adaptive algorithm for adjusting BP algorithm learning rate,under adaptive adjustment of wavelet coefficients and network weights,the efficiency of convergence was improved.Based on monitoring data of the four-lane Qian-ou tunnel,BP wavelet neural network prediction model is established.For the similar geological conditions and the same construction and initial support,BP wavelet neural network prediction of the tunnel-section de... |
