摘要
为科学评估并量化堤防工程失事风险,从致灾因子的危险性、孕灾环境的敏感性、承灾体的脆弱性和防灾减灾能力4个方面构建堤防风险评价指标体系。在通过解释结构模型(ISM)分析指标间作用关系及层级结构的基础上建立网络结构,利用网络分析法(ANP)确定权重;并基于改进的混合型中心点三角白化权函数进行灰色综合评价,从而确定堤防综合风险等级。以武汉市域某段堤防为例开展风险评价,得出其最大综合聚类系数为0.309,对应的评价结果为较高风险,并与传统AHP法对比验证了所提模型的科学性和适用性。
In order to scientifically evaluate and quantify the risk of dike project failure,a dike risk evaluation index system was constructed from four aspects of the hazard of hazard factors,the sensitivity of the disaster inducing environment,the vulnerability of the disaster-bearing body,and the ability of disaster prevention and mitigation.The network structure was established on the basis of analyzing the relationship between the indicators and the hierarchical structure through the interpretive structure model(ISM),and the analytic network process(ANP)was used to determine the weight.Based on the improved hybrid central point triangle whitening weight function for gray comprehensive evaluation,the comprehensive risk level of the embankment was determined.Taking a certain section of the dike in Wuhan City as an example to carry out risk evaluation,the maximum comprehensive clustering coefficient is 0.309,and the corresponding evaluation result is higher risk.Through compared with the traditional AHP method,the scientific nature and applicability of the proposed model are verified.
