| 摘 要： | 某水利枢纽的溢流坝为曲线型重力坝，由两边各２孔（高挑坎）和中间４孔（低挑坎）组成。选取了两种不同粒径的散粒体模拟基岩研究下游消能，试验测了水舌入水形态和相关的一些水力学参数，试验结果表明，该工程坝的基础、右侧电厂和尾水渠导墙未受到冲刷破坏，溢流坝的泄流能力满足设计要求。

| Abstract: | The spillway dam of a project is a curved gravity dam. It consists of 2 discharge orifices with high flip bucket in the both sides and 4 orifices with low flip bucket in the middle part. The experiment of energy dissipation selects 2 non-coherent materials of different particle sizes to simulate the rock bed below dam. The pattern of the jets entering into water and the correlative hydraulic parameters are measured. The experimental result shows that the dam foundation, power station at right side and guide wall of tailrace is safe from scour. The discharge capacity of the spillway dam meets the designed demand. |
