Abstract
In order to effectively solve the problems of fuzziness and randomness existing in the process of rock quality evaluation of dam foundation,a new approach of comprehensive evaluation on rock quality of dam foundation is proposed based on cloud model after analyzing the influence factors and grading standards.First,by means of constructing the antecedent and consequent cloud models and the uncertainty reasoning of cloud,the qualitative comment of each evaluation index is quantified into specific score value.Then,combined with the weight coefficient of each evaluation index,the total scores of dam foundation rock needed to be evaluated are obtained,which are helpful to determine the quality level.The results of case analysis and contrastive study indicate that this approach is feasible,moreover,the calculation steps are simple and the method can be easily realized by programming,which provides new ideas and means for the evaluation on rock quality of dam foundation.关键词
