Comparison on Dam Risk Consequences Comprehensive Evaluation Model
Many evaluation factors are involved in dam risk consequences comprehensive evaluation, which exist plenty of uncertainty and correlation between each other. Combined the five methods, such as linear weighted sum method, fuzzy mathematics method, matter element method, gray correlation method and principal component method with dam risk consequences comprehensive evaluation, establishing five dam risk comprehensive evaluation models, applying to the level evaluation of Changlong Reservoir, Xialan Reservoir, Shibikeng Reservoir, Longshan Reservoir, Lingtan Reservoir successfully. Based on this, in terms of evaluating methods, evaluating key technology, evaluating basic steps, weight determination methods, evaluation conclusions meaning and using difficulty, etc, dam risk comprehensive evaluation models are compared comprehensively. Finally these five reservoirs are divided into three types, and dam risk consequences evaluation model based on linear weighted sum method is recommend first.
