Study of Transportation Corridor of the Dangerous Mountainous Areas Based on GIS

Article Preview

Abstract:

As the geological hazards in mountainous areas in Southwest of China has the characteristic of different varieties, wide distribution and great harm. So, it is important to conduct the roads in scientific and rational method under the changing environment, especially to choose the traffic corridor with lower risk. In this paper, including the contents of analyzing the factors which influence the disaster risk and using the analytic hierarchy process with GIS spatial analysis to evaluate the disaster risk level of the mountainous areas of the traffic corridor under the given example-Sichuan-Tibet Railway from Changdu to Kangding.
