摘要
Abstract
Taking a highway slope case in Yunnan as the research background,this article established a stability evaluation index system for existing soft rock slopes,comprising 6 first-level indicators(topography,hydro-meteorology,stratigraphic lithology,rock mass structure,human engineering activities,and deformation characteristics)and 19 second-level indicators.The Saaty's 1-9 scaling method was adopted to determine indicator weights via Analytic Hierarchy Process(AHP).A unified formula for calculating membership degrees of qualitative and quantitative indicators was proposed based on the equivalence principle of fuzzy classification membership functions.A fuzzy AHP model was constructed and applied to comprehensively evaluate the slope stability.Quantitative analysis was then performed using the Strength Reduction Method(SRM)in midas-GTX-NX software.Results show that:the AHP-FCE qualitative analysis classifies the slope as marginally stable;SRM calculations yield safety factors of 1.10(natural conditions),1.04(saturated conditions),and 1.01(prolonged heavy rainfall conditions),all indicating marginal stability;both qualitative and quantitative analyses confirm the marginally stable state of the slope,necessitating effective reinforcement measures.关键词
