摘　　要：针对高速公路桥梁抗水毁稳定性问题,以经典模糊评价方法为基础,融合人工神经网络算法,提出更加满足工程实际需求的模糊-神经网络的综合评价方法,利用层次分析法确定各项评价指标的权重,以此建立高速公路桥梁抗水毁稳定性评价体系。通过将该评价体系运用于某山区特大桥抗水毁稳定性研究,判断某桥梁抗水毁设计的安全性。In view of the stability of highway bridges against water damage,based on the classical fuzzy evaluation method and the artificial neural network algorithm,a fuzzy neural network comprehensive evaluation method is proposed to meet the actual needs of the project,and the weight of each evaluation index is determined by the analytic hierarchy process,so as to establish the evaluation system for the stability of highway bridges against water damage.By applying the evaluation system to the study of the stability against water damage of a large bridge in a mountainous area,the safety of the design against water damage of a bridge is judged.
