基于FAHP防洪保护区洪水风险分析的溃口选择研究

针对溃口位置选择的重要性,结合洪水风险图溃口位置确定原则,构建溃口选择指标体系,根据建立的模糊互补矩阵,运用改进的模糊层次分析法确定各项评价指标的权重;然后,运用专家打分法得到各项指标的评分值;最后,利用各项指标权重和指标的专家评分值对备选堤防段进行综合评价。并结合黄河宁夏中卫河北段溃口选择实例进行分析,以此说明模糊层次分析法在洪水风险图溃口选择过程中应用的科学合理性。

Research on burst location choice of flood risk analysis in flood protection area based on FAHP

In accordance with the importance of burst location choice and combining the principle of determining the burst location of flood risk map,the paper constructed an index system of burst location choice.According to fuzzy complementary matrix,this paper determined the weight of each evaluation applied by improved fuzzy analytic hierarchy process;secondly,this paper aims to get the evaluation value each index through experts grading system;thirdly,according to the weight and the value of indexes,this paper carried out a comprehensive evaluation to alternative dike segment.This paper combined with the breach selection example of the northern section of Zhongwei of Yellow River in Ningxia to demonstrate the scientific rationality of FAHP in the breach selection process of flood risk map.
