摘　　要：根据突变理论及陈蔡水库自身运行状况建立了陈蔡大坝综合安全评价指标体系,对评价总目标进行了多层次矛盾分解,利用突变理论同模糊数学相结合产生的突变模糊隶属函数,由归一公式进行综合量化运算,最后得出陈蔡水库综合安全评价指标值。结果表明,该方法能有效地评价陈蔡水库安全,同时能反映出影响该水库安全运行的最不利因素——坝肩绕渗。Based on catastrophe theory and the operation status of Chencai Reservoir, a comprehensive safety evaluation index system is firstly established. Then the overall objective with multiple levels of conflict is decomposed, the mutation fuzzy membership function produced by the combination of catastrophe theory and fuzzy mathematics is utilized and the comprehensive integrated quantitative calculation is conducted by using normalization formula. Finally, the comprehensive safety evaluation index value is got. The evaluation result shows that the method can effectively evaluate the safety of Chencai Reservoir and can reflect the most unfavorable factors, i.e. seepage around dam abutments.
