摘　　要：管涌是一种主要的堤防渗透破坏形式,其受到堤防工程地质条件和水雨情等水文条件的综合影响,建立可考虑实时水雨情的堤防工程管涌动态安全评估方法,对于科学抵御洪水灾害,具有重要意义。通过梳理长江流域易发生管涌险情的堤防地基结构,分析了影响堤防安全的主要因素,构建了考虑实时水雨情的长江流域典型堤防管涌安全评估指标体系。分别通过敏感性分析和层次分析法,对各评估指标进行客观和主观赋权,再将主客观权重进行融合后,综合确定堤段安全评估值,进而建立了可考虑实时水雨情的长江流域堤防工程管涌动态安全评估方法。最后,以岳阳和武汉长江干堤部分堤段为例,验证了所提堤防工程管涌安全评估方法的有效性。Piping is a major type of seepage failure that is affected by the dike engineering geological conditions and hydrological conditions such as water and rain conditions. The establishment of a dynamic safety assessment method for dike engineering piping that can consider real-time water and rain conditions has practical significance for scientifically resisting flood disasters. This paper summarized the foundation structure of embankments in the Yangtze River Basin that are prone to piping hazards, analyzed the main factors that affect the safety of the embankments, and constructed an evaluation index system for the piping safety of typical embankments in the Yangtze River Basin considering real-time water and rain conditions. Through sensitivity analysis and analytic hierarchy process, each evaluation index was weighted objectively and subjectively, and the subjective and objective weights were combined to comprehensively determine the safety level of the embankment project. And then a dynamic safety assessment method for the piping of the embankment project in the Yangtze River basin was established, which can consider real-time water and rain conditions. Finally, the effectiveness of the new dike project piping safety assessment method was verified using Yueyang and Wuhan Yangtze River main dikes.
