层次分析法-可拓学模型在岩质边坡稳定性安全评价中的应用
Application of AHP-extenics model to safety evaluation of rock slope stability
摘要
Abstract
In order to solve the mining technical problem of the orebody outside the boundary,the theory of extenics about the matter-element concept and the analytic hierarchy process (AHP) were applied to establish a multi-layer comprehensive evaluation model of rock slope stability,thus the slope stability was evaluated and the safety level standard and the evaluation index were obtained.Firstly,the weight vector about the safety index was determined by AHP which influenced the slope stability,the elements in classical and joint field,correlation function of matter elements in extension sets were structured by extenics theory,an AHP-extenics model of rock slope stability was set up with comprehensive evaluation and then the safety evaluation result of rock slope stability was obtained.Through the calculation of the model,the safety index is 2.19 and the security level is Ⅰ,which means that the comprehensive safety level of the rock slope is hyper-stable.The research results are consistent with those of the RMR method and BQ method.关键词
