APPLICATION OF RMR BASED FUZZY AHP METHOD TO ROCK MASS CLASSIFICATION

  • 摘要: 传统的RMR法采用固定评估因素、固定评分方式进行岩体分级,其评分过程中存在着许多不确定性和主观性,在地质条件复杂的情况下岩体分级效果差。为了改变RMR法存在的不足,本文在参考RMR法的基础之上,提出了将AHP法应用于岩体分级的方案,给出了模型计算流程。将岩体分级看作一个多属性决策问题,根据实际情况可随机加入或减少影响岩体质量的评估因素,集合专家的意见重新确定各评估因素的权重值、建立相应的评分准则,然后通过迭代法计算岩体质量总评分再进行岩体分级。针对AHP法无法解决的模糊问题,在模型计算流程中引入了模糊理论进行相关处理,并编程实现该流程。最后将此方案应用于大湾隧道进行岩体分级,分级结果与RMR法的结果进行对比分析,结果显示模糊AHP法的岩体分级结果与实际情况更加吻合。
