Stability Evaluation and Hazard Analysis of Mountain Road Slopes Based on AHP Method
On the basis of in-depth research on the landslide disasters on both sides of mountain roads,the stability and degree of harm were analyzed and discussed.For slope stability,the qualitative method of stereographic projection and the quantitative method of limit equilibrium were used to study and calculate its stability degree.Three influencing factors,namely"traffic volume,scale,and height,"have been determined to determine the degree of harm caused by landslides on mountainous roads.On this basis,this article assigned weights to each factor,constructed relevant formulas,calculated the membership degree of each indicator,and established a functional relationship between membership degree and indicators.Thus,the AHP method can be used to analyze the degree of harm to specific slopes.On the basis of determining the stability of the slope and the degree of collapse hazards,the danger of collapse hazards can also be further determined.
