摘　　要：为研究清远抽水蓄能电站溃坝对下游梯级水库和防洪保护区的影响,利用MIKEFLOOD构建一二维耦合模型对溃坝洪水演进进行模拟。研究共设置12种工况,分析不同因素对溃坝后洪水流量、淹没范围、淹没水深等演进过程的影响。结果显示,溃决形式(溃口宽度)及溃决水位、溃决历时都是影响溃坝洪水的重要因素,且梯级电站溃坝后对于距离较近且地势较低的楼心村、大楼村影响最为显著,应采取相应预防措施。In order to study the impact of dam break of Qingyuan pumped storage power Station on downstream cascade reservoir and FLOOD protection area,a two-dimensional coupling model was constructed by using MIKE FLOOD to simulate the evolution of dam break flood.A total of 12 working conditions were set up to analyze the influence of different factors on the evolution process of flood flow,inundation range and inundation depth after dam break.The results show that the form(width of the breach),the level of the breach and the duration of the breach are all important factors affecting the flood of the dam break,and the impact is most significant on the villages of Louxin and Daolao,which are close and low lying,and corresponding preventive measures should be taken.
