摘要
Abstract
This study investigated the seismic response of hydraulic tunnels by establishing a finite element model.Multiple prediction models were developed using various algorithms based on machine learning theory,and the optimal machine learning method for this simulation was identified.Furthermore,a parameter sensitivity analysis of the hydraulic tunnel was conducted based on the optimal prediction model.The results show that the finite element model of the hydraulic tunnel's seismic response has good accuracy.Among the seismic response prediction models established using the simulated data,the random forest algorithm proved to be the optimal prediction model.The sensitivity analysis indicated that the maximum circumferential tensile stress and the maximum radial tensile stress are most sensitive to the tunnel's burial depth.The research findings can provide valuable references for tunnel design and management.关键词
