【摘要】 在综合分析影响震后公路边坡各种因素的基础上,选取地形地貌条件、构造条件、地层条件、水文地质条件和其他因素作为一级评价因子,下分边坡坡形、坡体结构、边坡坡度、边坡坡高、细观构造、出露结构面和地层岩性等15个二级评价因子;应用模糊数学理论和方法,建立分析边坡稳定性的综合评判层次模型,评价了S303线映秀-卧龙段K0+650～K0+865处震后边坡的稳定性。结果表明:该方法的评判结果与选取边坡实际情况基本一致,可为震后公路边坡稳定性评价提供一定的借鉴。更多还原

【Abstract】 Based on comprehensive analysis of various factors of post-earthquake highway slope,selecting some factors including geographic and geomorphic conditions,structure conditions,stratum conditions,hydrology geology conditions and other factors as first-grade factors,these first-grade factors were divided into 15 second-grade factors such as slope configuration,slope structure,slope gradient,slope height,exposed structure surface and lithology and so on.And then the AHP theroy was applied to determine weight factors affecting the stability of post-earthquake highway slope and the fuzzy comprehensive evaluation(FCE ) was used to establish comprehensive evaluation model applied to analyze slope stability by using fuzzy mathematic theory and method.Finally according to this model,stability of the slope of K0+650～K0+865 in S303 from Yingxiu to Wolong was analyzed.The innovation of this thesis lies in one new uncertain stability grade appraise method of post-earthquake highway slope.The results show that the theoretical results agree well with the actual condition.In addition,it provides certain reference significance for stability evaluation of post-earthquake highway slope in the future.更多还原
