| 摘 要： | 公路洪灾是一个多因素耦合的复杂系统,本文针对公路洪灾风险的复杂性、模糊性及不确定性,构造了基于熵权的模糊综合评价模型,通过熵权使权重由主观判断转为由各指标数据之间的关系来确定,从危险性和易损性两方面选取24个评价因子,定量地对重庆境内渝黔高速公路进行洪灾风险评价。评价结果表明,熵权模糊综合评价法是科学可行的,为公路洪灾风险趋势预测以及风险等级划分提供了良好的分析方法,在实践中具有一定的应用价值。

| Abstract: | Road flooding is a multi-factor coupling complex system.Aiming at the complexity,ambiguity and uncertainty of the road flood risk,constructed a fuzzy comprehensive evaluation method,which based on entropy weight which is determined by the relationship between the respective indicator data.Twenty-four factors were selected from both risk and vulnerability in flood risk for quantitative assessment in Chongqing-Guizhou Expressway in Chongqing.The result shows that fuzzy comprehensive evaluation method based on... |
