The Research of Hazard Degree on Landslide of Highway in Southwest Mountainous Based on Improved Analytical Hierarchy Process

摘要：

　　This paper study disastrous factors for landslide by means of qualitative analysis by the improved analytical hierarchy and establish the analytical hierarchy chart of disastrous factors for landslide and the pairing comparison matrix.Taking characteristic vectors of the pairing comparison matrices as the weights of assessment factors for landslide, the influence order of the assessment factors are determined.Effect index of disastrous factors for landslide and decide model are set up.The grade of landslide hazard degree was defined.The model is applied to assess the hazard degree for landslide.Result obtained has a high relativity to the real situation.The study indicates that this kind of assessment is feasible and veracious for the assessment of landslide danger degree.They provide a basis forwarning and control of landslide .
