    摘要:

    在综合分析山区堤防工程自身特性及其运行条件的基础上,结合行业规范及相关专业研究成果,构建了包含降水强度、河道形态、堤身材料、堤身渗透性及历史险情等17个评价指标的山区堤防安全评价指标体系,通过改进层次分析法和基于平均差的CRITIC法对评价指标进行主观和客观赋权,并基于博弈论组合赋权,提出了一种改进组合赋权的山区堤防安全云模型评价方法。对清远市某山区堤防工程安全云模型评价结果表明,该山区堤防工程的安全评分为706,安全等级为基本安全,与工程实际情况相符,验证了该评价方法的可靠性和合理性,可用于山区堤防安全评价。

    Abstract:

    On the basis of comprehensive analysis of the characteristics and operating conditions of mountain levees, combined with industry standards and related professional research, a mountain levee safety evaluation system with 17 evaluation indexes was constructed, including rainfall intensity, channel shape, dike material, dike permeability, historical danger, etc. The indexes were weighted subjectively and objectively by improved analytic hierarchy process and CRITIC method based on average difference, and an improved combined weighted cloud model evaluation method was proposed based on game theory. The proposed improved method was applied to the safety evaluation of a mountain levee project in Qingyuan. The calculation and analysis show that the safety score of the mountain levee project is 70.6, and the safety level is basic safety, which is consistent with the actual situation of the project. The reliability and rationality of the levee safety evaluation method proposed in this paper is then verified, and it can be used for the levee safety evaluation in mountain area. Keywords: embankment in mountain area; safety evaluation; cloud model; combination weighting; analytic hierarchy process; CRITIC method 〖FL
