摘　　要：由于堤防溃决后灾害损失严重,世界各国对于溃堤洪水与堤后冲刷问题均给予了高度的重视。从理论研究、数学模型计算和物理模型试验3个方面对该问题进行了综述。概括总结了目前国内外溃堤洪水冲刷研究的发展历程、研究进展和相关成果,分析归纳了3种研究手段的优势与存在的问题,认为目前单一手段难以满足现阶段溃堤洪水与堤后冲刷研究的需要。如何建立一个适用范围广、模拟精度高、能发挥各种研究手段优势的综合研究方法是未来该问题研究的重要方向。今后仍需加强溃堤洪水与堤后冲刷问题的理论研究,并加大试验监测设备的开发力度,为防洪减灾提供有力的技术保障。Due to the serious consequences of dike break, researchers all over the world have paid great attention to dike-break flood and scouring. In this paper, we made a review on dike-break flood and scouring from aspects of theoretical research, mathematical model, and physical model test. We summarized the development, research progress, and achievements in this regard, and by depicting the advantages and shortcomings of the aforementioned three research approaches, we reckon that single approach does not meet current requirements on the study anymore. Developing a comprehensive research method integrating various approaches with wide application scope, high simulation precision could be a crucial direction for future research. Moreover, theoretical research should be strengthened, and development on monitoring instruments should be also intensified to offer technical support for flood control and disaster prevention.
