对高坝下游水垫塘内的淹没冲击射流进行了详细的分析 ,并在 1 :40 0的溪洛渡精细模型上利用热膜测速仪量测了中孔泄流工况下水垫塘内的水流结构 ,给出射流在水垫塘内的衰变规律 ,初步探讨了水垫塘的消能机理
The submerged impinging jets in the plunge pool at the downstream of the high dam were analyzed in detail, and the water flow structure in the plunge pool under the mid-hole discharge condition was measured by the hot-film anemometer on the 1:40 scale Xiluodu fine model The decay law of jet flow in the plunge pool initially discussed the energy dissipation mechanism of the plunge pool
