摘要
针对评价洞室围岩质量3种传统方法(RMR法、Q法、HC法),结合可拓学理论,建立各自围岩质量评价的物元模型。首先采用层次分析法对各模型中的评价因素予以分级,确定各指标的权重及其与围岩级别的关联度;然后利用集对分析法对各模型在综合评价中的关联因子予以确定,形成洞室围岩质量多层次综合评价模型;最后将该模型应用于西南某大型水电站地下洞室围岩质量评价中,计算结果与现场评价结果较吻合。研究结果表明:该模型将传统评价方法进行了有机结合,最大限度降低了各方法的缺陷性,可较好地反映洞室岩体的质量等级,对洞室围岩分级具有一定指导意义。
Based on three traditional cavern rock quality evaluation methods（RMR、Q、HC）,combined with extension engineering theory,each rock mass quality matter element model is established.Its weight aggregation and relational degree of the actual cavern rock quality grades are calculated by using the stratification analysis method.Then,each relational index result of three traditional cavern rock quality evaluation methods is acquired by way of the set pair analysis（SPA）.Hence,the multi-level comprehensive evaluation model（MCEM）can be achieved with the above results.The MCEM method is applied to a hydropow-er project in the southwest of China in order to test its feasibility.It is shown that the integration of MCEM method with three traditional methods can reduce the defect of each traditional method.It reflects more precisely the quality classification of the cavern rocks,and thus can be used to improve the cavern rock quality evaluation to some extend.
