At present,the infrastructure construction represented by highways is in the stage of rapid development.However,the choices of highway routes in the mountainous area with complex terrain are limited by many factors,especially geological factors.A good and scientific project of choice of highway route will directly affect the economic development of the country or the region and the life period of the whole project.Therefore,it is necessary to summarize a set of principles for the choice of highway routes and establish a set of evaluation systems with strong feasibility and high practicability of choice of highway routes in complex mountainous areas.Taking the project of Leshan to Hanyuan highway(Hanyuan parts),the paper studies the choice of highway route according to the engineering project under a special geological environment and summarizes the corresponding choice principles of highway routes and establishes the evaluation systems of highway routes considering the geological factors.The main achievements of this paper are as follows:1.Summarizing choice principles of highway routes in mountain areas.Taking the project of Leshan to Hanyuan highway(Hanyuan parts)as an example,considering the influence of engineering geological conditions on route choice the paper puts forward corresponding choice principles of highway route in complex mountainous areas.Focusing on complex geohazards such as landslide,debris flow,collapse,bedding slope,special rock and soil,and combining with the engineering examples of Leshan to Hanyuan highway(Hanyuan parts),the paper reveals the difficulty of route choice and puts forward the corresponding choice principles of highway routes.2.Referring to the project of choice route of tunnels and bridge in Leshan to Hanyuan highway(Hanyuan parts),the choice principle of tunnel and bridge routes are summarized.The choice of the tunnel route is studied from two aspects: one aspect is to analyze influencing factors on the view of geology aspect;the other aspect is to use Midas software to establish the tunnel mechanical model for analyzing the stress form of the tunnel.At last,the paper put forward the corresponding choice principles of tunnels.The research on bridge geological route selection mainly focuses on the relationship between the geological conditions and the choice of bridge route and puts forward the choice principle of bridge route.3.Establishing a system of choice of highway routes.Influencing factors on route choice of the highway are quantified via professional person filling the questionnaires.The AHP method is used to determine weights and the priority of influencing factors on the route choice of highways.The above research results offer a theory for route choice of highways.
