摘要
针对目前围岩稳定性等级评价方面存在的缺陷,考虑影响围岩体稳定性的主要因素,提出了一种基于层次分析法(AHP)和物元模型的综合评价系统。以围岩稳定性等级、评价指标及其特征值构造物元模型,同时采用层次分析法计算各评价指标的权系数,并根据计算出的综合关联度来实现对各围岩稳定性等级综合评判。以某水电站2号导流调工程实例验证了该系统的科学性、可靠性以及适用性。
According to the problem of grade evaluation about wall rock, combined with some factors that influence stability of wall rock, a practical synthetic evaluation system is given out based on analytic hierarchy process and matter elements model. This method takes the grade of wall rock, evaluating index and its characteristic value as matter elements and adopts analytic hierarchy process AHP to establish weight aggregation, and the grade of the wall rock samples and its optimum order are brought out according to the. The engineering example shows, the synthetic evaluation system is scientific, reliable, applicable.
