摘　　要：结合某水库工程的实际情况,在考虑水库洪水调节的基础上对水库大坝坝顶高程进行复核分析,研究水库工程的防洪能力。通过现场调查,水库调洪原则同原设计方案一致,经过复核溢洪道泄流量情况,获取水库洪水调洪曲线,结合波浪高、安全加高等因素影响,综合确定不同工况下水库坝顶高程要求,经复核,水库大坝坝顶高程满足要求。研究结果可为水库安全运行提供参考。Based on the actual situation of a reservoir project and considering the reservoir flood regulation,the dam crest elevation of the reservoir is reviewed and analyzed to study the flood control capacity of the reservoir project.Through field investigation,the principle of reservoir flood regulation is consistent with the original design scheme.After reviewing the discharge of the spillway,the reservoir flood regulation curve is obtained.Based on the impact of wave height and safety enhancement factors,the requirements for reservoir dam crest elevation under different working conditions are comprehensively determined.After review,the dam crest elevation of the reservoir meets the requirements.The research results can provide reference for the safe operation of reservoirs.
