| 中文摘要: |
| 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。 |
| 英文摘要: |
| The working principle of throat-type energy dissipator is similar to that of orifice dissipator by which the energy of high speed flow is dissipated by means of sudden contract and sudden enlargement of cross section in the tunnel,and the former is excellent with the feature of simple structure,stable flow,rare cavitation phenomena, etc.The validity of the hydraulic calculation is verified by model test. |
