Abstract
In order to solve the problem of quality evaluation of toppling rock mass,the concept of matter-element in extenics theory and fuzzy analytic hierarchy process were comprehensively employed to determine the quality of the rock mass at different depth through samples in the horizontal position of No.9 adit at the left abutment in Miaowei Hydropower Station.According to the field experimental data and the existing rock mass quality evaluation method,the safety grade and the value of the evaluation indexes were obtained.The weight factors of the indexes were determined by FAHP incorporating with fuzzy mathematics.Based on the classical matter-element,joint domain,and correlation function in extentics theory,the FAHP-extenics model of toppling rock mass quality evaluation was built.The research shows: the sample quality grade evaluated by FAHP-extenics model is lower than that of RMR;FAHP-extentics model is able to consider the characteristics of toppling rock mass and better reflect the rock quality.关键词
