摘　　要：通过对已发生的面板坝溃坝事故研究发现,面板坝溃决过程是局部逐渐未溃到底溃坝模式。通过建立混凝土面板坝溃决过程物理模型,并进行模拟计算,得到不同时间面板折断高度与下泄流量的关系和溃坝下游河道沿程流量变化情况,并由此得出溃坝过程中下泄流量的变化趋势。通过实例研究,验证了该方法的合理性和有效性。According to the study on the occurred breach accidents of the dam with face slab, it is found that the outburst process of such dam is in the pattern of local through full breach process. Through the establishment of the outburst process of physical models for simulation calculation, this paper gets the relation between the broken heights of face slab at different times and its releasing discharge, and the discharge change process along downstream fiver channel. Then it gets the change tread of releasing discharge in the process of dam breach. Case study proved this model is reasonable and effective.
