Slope Stability Analysis Based on Fuzzy Analytic Hierarchy Process
In order to quickly and effectively analyze the stability of the slope,a fuzzy hierarchical analysis method is proposed to conduct a comprehensive evaluation of the slope stability.Combined with the actual engineering site investigation,the fuzzy analytic hierarchy process evaluation index,fuzzy membership function and weight are determined,and finally,a slope stability evaluation model based on hierarchical analysis is established.According to the established model,the stability of the slope in the west area of Putian University is evaluated and compared with the traditional slope stability analysis.The results show that fuzzy hierarchical analysis comprehensively considers the influencing factors such as rock mass integrity,rock mass weathering degree,mechanical properties of rock and soil,joints and fissures,rock layer occurrence,slope angle,precipitation,earthquakes and human activities,etc.,and can effectively and quickly evaluate the slope stability.
