摘　　要：针对目前大坝安全评价方法中均未考虑评价指标的模糊性和随机性问题,综合考虑土石坝变形、渗流及环境三方面因素构建了土石坝安全评价指标体系,将正态云模型引入到土石坝安全评价中,利用投影寻踪法确定各评价指标权重,提出一种基于投影寻踪—正态云模型的土石坝安全综合评价模型。实例应用结果表明,土石坝安全评价结果为低风险,与实际情况相符。可见所建模型可行、有效。According to the lack of study on fuzziness and randomness of evaluation index in dam safety evaluation method, a safety evaluation index system based on deformation, seepage and environment of rock earth dam has been constructed. A model based on projection pursuit analysis and normal cloud model has been established to evaluate safety degree of rock earth dam. The projection pursuit analysis was used to compute the assessment indicator＇s weights. Examples of application results show that the rock earth dam＇s evaluation is in low risk and it accords with the actual situation. So, the proposed method is feasible and effective.
