基于FAHP的功效系数法的岩质边坡稳定性分级
Stability Classification of Rock Slope Based on FAHP Efficiency Coefficient Method
摘要
Abstract
According to the characteristics of fuzzy evaluation of rock slope stability and multi index,using fuzzy AHP to determine the weight of the first and second level indicators,we improve 0.1 -0.9 scale method of index weight and subjectivity and overcome the singularity,and avoid the inconsistency of the same index to quanti-fy the discontinuity based index.The efficacy coefficient method is introduced to solve the numerical normalization method for different types of basic indexes.The total effect is calculated with the numerical efficiency of the numer-ical simulation and the first and second level index weight vector,according to the general efficacy coefficient size stability level.On the basis of Fuzzy AHP,the results of stability evaluation and classification of rock slope in Yongji correspond to the actual situation,which proved that the method has good applicability and reliability for the stability classification of rock slope.关键词
