摘　　要：随着全球极端气候越发频繁、水资源时空分布更加不均,水资源供需矛盾日益加剧。为充分利用水库调控水资源能力和发挥工程效益,采用预蓄预泄法对燕山水库汛限水位进行动态控制方案研究,首先基于下游防洪安全,根据降雨与洪水预报信息,采取预蓄预泄方案确定汛限水位上限值;再基于大坝自身安全和水库超泄能力分析确定了主汛期与后汛期的最高汛限水位。与原汛限水位104.20 m相比,考虑洪水预报信息情况汛限水位可调整至104.77 m,考虑降雨预报信息时可调整至105.36 m。计算分析结果表明,调整后的动态汛限水位对大坝自身安全及下游防洪安全影响较小,提高了水资源可利用率,具有可实施性。With the global extreme climate becoming more frequent, more uneven temporal and spatial distribution of the water resources has resulted in an increasing contradiction between supply and demand of the water resources. In order to make full use of the reservoir water resources and develop the reservoir＇s engineering benefit, analyses and studies of the control scheme of the flood control level for the Yanshan reservoir have been carried out by using a prestorage and predischarge method. First, taking the downstream flood control safety into account, with the help of the rainfall and flood forecast information, the upper limit of the flood control level was determined by the prestorage and predischarge scheme; then based on the dam safety, considering reservoir ultimate discharge capacity, the highest flood control level during the major flood period and post-freshet period was determined. Comparing with the original flood control level of 104.2 m, the new flood control level considering flood forecast information can be adjusted to 104.77 m, and the flood control level considering the rainfall forecast information can be adjusted to 105.36 m. The calculation and analysis results show that the adjusted dynamic flood control level of the reservoir, with a slight influence upon the dam safety and downstream flood control safety, can greatly improve the utilization rate of the water resources, hence applicable and implementable.
