| 摘 要： | 针对水动力条件变化复杂、水土耦合作用强烈的土石坝溃决过程,结合水库调洪演算、清水冲刷以及溃口冲刷侵蚀机理,在Breach模型基础上建立了土石坝漫顶溃口流量过程计算物理模型。结果表明:模型对JP水库大坝溃决过程的模拟,很好地再现了溃决洪水流量过程线、溃口展宽和下切过程,验证了模型的合理性和应用潜力。

| Abstract: | Aimed at the break process of earth-rock dam of complicated change of water dynamics condition and strong water soil couple effect and combined with reservoir flood regulation, clear water scouring and mechanics of breach erosion invasion,this paper set up a physically based numerical model to simulate the overtopping break process of earth dam on the base of breach model.This model was applied to the simulation of break process of JP reservoir dam,and reproduced the flood flow process of dam-break,breach width and progression process and verified the rationality and application potential of the model. |
