我国高坝泄洪消能研究的最新进展

近些年来,我国一直处于水电开发与建设的高峰期,大量的实际需求促进了高坝泄洪消能技术的发展与进步。本文分4个方面总结了近年来我国在高坝泄洪消能研究方面的最新进展情况：（1）高拱坝坝身泄洪消能;（2）高水头大流量底流消能;（3）高水头大流量溢洪道与泄洪洞的水力学问题;（4）泄洪雾化问题。在总结已有研究成果的基础上,对高坝泄洪消能技术的进一步发展,以及与之相应的环境问题及安全运行管理等提出了若干建议。

Summary of research on flood discharge and energy dissipation of high dams in China

China is now experiencing a fast igium period for hydropower development and dam construct ion. Many problems come across in pract ice of dam building have accelerated development and advancement of dam hydraulics. This paper presents a summary comment on research progress in the flood discharge and energy dissipation of high dams in the country. The main content includes four aspects: flood discharge and energy dissipation in high arch dams; energy dissipation by hydraulic jump in st illing basin with high head and large flow rate; spillways and flood tunnels, and atomization due to flood discharging. After reviewing the research achievements, some suggest ions for the high-dam flood discharge and energy dissipation are proposed in terms of further development, environmental impacts and operation and supervise of hydraulic structures.
