摘要
基于集对分析法原理,采用围岩等级分类中RMR围岩分类方法,建立围岩分类等级的评价体系;结合层次分析法原理,根据RMR围岩分类等级和实际工程经验得到各指标的权重值;利用集对分析法中"同、反、异"原则求得各指标联系度以及加权联系度,根据最大隶属度原则确定围岩等级.结合某大型水电站地下洞室围岩RMR分类的实测数据,基于集对层次分析法的原理进行研究,计算结果与已有研究结果基本吻合,可以作为研究围岩等级的新方法.
Based on set pair analysis principle and RMR classification, a method of surrounding rock evaluation system of classification is established. According to the RMR classification of surrounding rock grade and practical experience, the principle of analytic hierarchy process is used, and the value of the weight of each index is obtained. Then a set pair analysis method ＂with the backward difference＂ principle is employed to obtain each index of connection degree and weighted connection degree. Finally, using the maximum membership degree principle to determine the grade of surrounding rock. Combined with a large RMR classification of surrounding rock of underground caverns of hydropower stations measured data, the calculation results agree with the existing research results. So it can be used as a new method of studying surrounding rock grade.
