【摘要】 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。更多还原

【Abstract】 China is now experiencing a fastigium period for hydropower development and dam construction.Many problems come across in practice 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 stilling basin with high head and large flow rate;spillways and flood tunnels,and atomization due to flood discharging.After reviewing the research achievements,some suggestions 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.更多还原
