Abstract Research purposes: With the rapid development of high-speed railway construction, there are many schemes about route selection of railway and many factors affecting route selection of railway, such as complicated engineering geological conditions and huge investment. The traditional route selection comparison generally takes the economic index as the main influence factor to measure the route selection. This paper analyzes the main factors that affect the route selection based on the Nanning-Shenzhen high-speed railway project, established the index system of decision-making for the route selection of Nanning-Shenzhen high-speed railway based on analytic hierarchy process, and considering the influence of many factors on the decision-making level, establishes the decision-making model of the route selection of high-speed railway based on analytic hierarchy process (AHP).
Research conclusions: (1) Comparison and selection of route scheme is an important content of design of railway line selection.When we conduct the comparison and selection of route scheme, the influencing factors such as project investment,difficulty of project implementation, and project risk should be considered synthetically in order to make sure the selected line scheme optimal.(2) The recommended conclusion of using analytic hierarchy process is the same as the route selection recommended scheme of Nanning-Shenzhen high-speed railway. (3) The route selection model of high-speed railway based on analytic hierarchy process can make up for the shortcomings of subjectivity and singleness in general route selection of high-speed railway, and the decision-making model is practical, reasonable and scientific. This paper can provide reference for the route selection of similar projects.
