Research on the Comparison and Selection of Road,Bridge,and Tunnel Schemes for High-speed Railway Based on Analytic Hierarchy Process
In the process of high-speed railway construction,how to reasonably select subgrade,bridge and tunnel schemes is very important.If the scheme is not selected properly,it is easy to cause economic losses,environmental damage,geological disasters and other problems,and even affect the safety of high-speed railway operation.Based on Jinhua-Jiande High-speed Railway project,this paper analyzes the main influencing factors of scheme comparison and selection through the comparison and selection of two typical road-bridge and road-tunnel schemes,and obtains the recommended scheme.Combined with the Analytic Hierarchy Process(AHP),the decision-making model of scheme comparison and selection of road-bridge and road-tunnel is established,and the comprehensive evaluation of the scheme is carried out,which verifies the scientificity of its application in scheme comparison and selection,in order to provide reference for future scheme comparison and selection methods.
