摘　　要：我国目前还存在相当数量的病险水库,在局部极端降雨或其他突发情况下,依然有很大的溃决风险。以山东省某水库为研究对象,分别利用逐渐溃模式和二维水动力模型进行溃口流量计算和洪水演进模拟,分析了漫顶溃决过程及影响并绘制淹没图,所得结果可为水库管理机构应对溃坝风险提供决策支持。There are many dangerous reservoirs in China,and the dam failure risk is very high under extreme weather and other emergency events in local regions.Taking a reservoir in Shandong Province as the research object,this paper calculates the break discharge,simulates the flood routing,analyzes the overtopping break process and impact,and draws the inundation map using gradual break model and two-dimensional hydrodynamic model.The results can provide decision support for the reservoir management organization to deal with the flood risk of dam breach.
