Taking the Baishiyan Tunnel section of the Huangbai Railway as the research object,the controlling factors of the route plan are analyzed.The first-level factors are terrain conditions,geological conditions,engineer-ing conditions,and environmental conditions,which are divided into second-level factors.A route plan factor evalu-ation system is established.The partial least squares path method is used to establish a plan comparison model,and the plans are compared to determine the optimal plan.The results show that the plan factor evaluation system can effectively classify the factors and evaluate the plan,and the established comparison model can effectively compare the plans and select the optimal plan.This study has certain reference value for railway route selection.
