摘要
针对堤防工程安全风险评估中传统安全系数法存在缺陷的问题,引进灰色理论,以堤基工程地质条件、河势稳定性、渗透稳定性、滑动稳定性、堤防整体性和工程管理为基本要素,构建堤防安全风险评价指标体系及堤防安全评价数学模型。将所建模型用于实例分析中,结果表明,该模型可行有效,可为堤防工程安全评价及除险加固提供参考。
Grey theory was employed to evaluate the safety risk of dyke structure and it can avoid the defects of traditional safety coefficient method.A mathematical model was built with a comprehensive evaluation index system： engineering geological conditions,regime stability,seepage stability,sliding stability,levee integrity and project management.Application of this model to practical engineering cases validated the theory and the proposed model that are useful for design of dyke rehabilitation.
