摘要
为解决缅甸DAPEIN(Ⅰ)水电站泥沙通过排沙管道或泄流口不致于淤塞库区且避免泥沙流入电厂的问题,分析了取水防沙原设计方案试验中存在的问题,指出冲砂底孔进口上延方案为最优取水防沙方案,探讨了该优化方案在不同工况下的取水防沙效果,提出了运行时应注意的事项。
For solving the problem of DAPEIN （ Ⅰ ）Hydroelectric Station in Burma, which defenses sediment through sediment dejection pipeline or outlet silting up reservoir area and avoids it inflowing into the hydroelectric station, in the paper, it analyzes the issue existed in the original scheme experiment of water-inlet and sediment control, points out that the optimal method is sand flushing bottom-hole extending to the upstream way, discusses the effect of the optimal method in different condition, puts forward events should be paid attention to.
