基于层次分析法的高速铁路路桥、路隧方案比选研究

Research on the Comparison and Selection of Road,Bridge,and Tunnel Schemes for High-speed Railway Based on Analytic Hierarchy Process

高速铁路建设过程中如何合理选用路基、桥梁、隧道方案至关重要,若方案选用不合理,易造成经济损失、环境破坏、地质灾害等问题,甚至影响高铁行车安全。文章依托金建高铁项目,通过两处典型路桥、路隧方案比选,分析了方案比选的主要影响因素,得出推荐方案,并结合层次分析法(AHP)建立路桥、路隧方案比选决策模型,进行了方案综合评价,验证了其在方案比选中应用的科学性,以期为以后的方案比选方法提供参考。

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.
