钢筋面网溢流堆石坝流态转换特性的试验研究

Research on the features of flow state conversion of reinforced surface net water-spilling and stone-piling dam

通过水工模型试验，探讨了不设置鼻坎的钢筋面网溢流堆石坝水流流态转换规律及其转换条件；提出了现有渠道堆石坝 可不设置鼻坎即能形成面流衔接的水流方式，具有节省投资和减轻下游冲刷等优点。

From water conservancy project medel experiment, this paper explored the flow state conversion regu- larity and conditions of nose - pit-free reinfoced surface net waterspilling and stonopiling dam. It also posed pr- esent existent ditchhead stone-piling dam which can be the noopit-free to form a waterflowing type of surface connecting. And it has the merits of saving investment and lightening erosion in the lower reaches of rivers
