摘　　要：针对喜河水库设计汛限水位在实际运行中存在的问题,从三方面分析了喜河水库实施汛限水位动态控制的可行性,讨论了不考虑预报和考虑预报的两种预泄调度模式下的水库汛限水位动态控制的原理,指出预泄调度需要确定的几个关键指标:预泄判别流量,预泄流量,预泄控制水位。以上述理论为依据,在分析喜河水库洪水规律的基础上,分别研究了不同预泄调度模式下喜河水库汛限水位动态控制上限值,通过拟定调度规则并对设计洪水进行调洪计算,验证了所确定的汛限水位的合理性。结合喜河水库所处的流域特点和入库洪水特点,最后确定了喜河水库主汛期防洪限制水位上限值为361.5m。To solve the practical problems in the operation of Xihe reservoir,the feasibility of limited level dynamic control is analyzed from three aspects.The control rule is discussed for the discharge mode with forecast and the mode without forecast.Some key indicators are analyzed,such as pre-discharge threshold flow,pre-discharge flow and pre-discharge water levels.Under the Xihe reservoir flood control rulest,he upper reservoir limited level is studied for different pre-discharge schemes.The flood control limited level is verified by adopting certain planning operation rules and through flood operation calculation and the maximum limited level is determined for Xihe reservoir.
