摘要
分析了堤防系统的层次性及模糊性,在此基础上建立了堤防工程风险评价系统指标体系和评价结构模型。结合FCT(Fuzzy Consistency Theorem)及AHP(Analytic Hierarchy Process)定义了模糊一致空间,实现了基于模糊一致矩阵的权重反演。针对各典型护岸段,通过加固前江堤系统风险评价的结论,实现了护岸工程的风险等级划分,进而按照局部与整体加固两种情况完成了加固后江堤系统的风险评价。
Dike construction risk evaluation system and risk evaluation definition model are settled down with the analysis of dike construction hierarchy as well as fuzzy character, Inclusive of Fuzzy Conststency Theorem and Analytic Hierarchy Process, with the definition of fuzzy consistency space, weight reverse analysis math model is realized. By the mnclusion of dike construction system risk evaluation for prefortification situation, dike bank safety constmetion risk grade is ranked for representative bank safety construction, by which, dike system risk evaluation for post-fortification situation is covered according to local fortification and integral fortification.
