本文提出的洞塞式消能工与孔板非常相似 ,充分利用高速水流经过局部突缩突扩断面产生巨大水头损失实现消能 ,但体型简单 ,洞塞内水流相对平稳 ,消能率很高。本文较为详细地介绍了洞塞消能的特点、洞塞泄洪洞的布置型式和水力学计算。水力学模型试验成果与计算结果非常吻合 The plug-in energy dissipater proposed in this paper is very similar to the orifice plate. It makes full use of the high-speed water flow to generate large head loss through local sudden expansion and expansion to achieve energy dissipation. However, the body shape is simple and the water flow in the plug is relatively stable and the energy dissipation rate is high. This paper introduces the characteristics of plug energy dissipation in detail, the type of layout and the hydraulics calculation of the plugging tunnel. The hydraulic model test results are in good agreement with the calculated results
