摘要：
Dam foundation rock mass quality evaluation is a multi-factor system process of synergy effect, in view of the problems existing in the evaluation process, the introduction of Cloud model, projection pursuit method and analytic hierarchy process(AHP) and fuzzy entropy theory, is put forward based on the improved Cloud-PP-AHP rock mass quality evaluation model for the two-dimensional. The model on the basis of rock mass quality evaluation index system and classification standard and evaluation index is calculated which belong to different quality levels of cloud model parameters;Based on hierarchy analysis and projection pursuit method to solve the combination weights of the indexes;Plug in the measured data of rock mass, for evaluation of rock mass is affiliated with various quality grades of integrated uncertainty;Assisted by fuzzy entropy E as the contestant, jointly build the rock mass quality grade evaluation of two dimensional evaluation model. Finally the model is applied to a hydropower station dam foundation rock mass quality evaluation, the evaluation results with other evaluation methods were analyzed, the results show that the model is applied to rock mass quality evaluation of effective and feasible, and the evaluation results intuitive, for rock mass quality evaluation provides a new way. © 2016, Science Press.
