水库汛限水位调整与运用

Adjustment and application of the limited level of reservoirs during the flood season

基于对水库汛限水位主要影响因素的系统分析,从洪水资源安全利用的角度出发,阐明了水库汛限水位调整综合分析论证所应遵循的原则,提出了风险设计分析论证的框架、定量分析方法和汛限水位合理调整的论证。最后以海河流域潘家口水库为分析实例,从设计洪水、预报预泄、洪水预报调度方式、上下游防洪设计标准、上游移民淹没及土地退赔线、水库长期运行的风险和效益等多个方面分析论证了水库汛限水位的合理调整方案。

Based on the systematically analysis of the major impact factors about the limited level of reservoirs during the flood season, and from the point of the view of safe utilization of flood resources, the paper illustrates the principles of analyzing, demonstrating and confirming comprehensively the limited level of reservoirs during the flood season, put forward the framework and the methods for the risk design, and details with the contents of adjusting reasonably the limited level of reservoirs during the flood season. Finally, taking the Panjiakou Reservoir in the Haihe River basin in China as an example, the paper analysis the reasonable adjustment scheme of the limited level of the reservoir during the flood season according to the design flood, the flood forecasting, the flood control operation under forecasting, the flood control standard of upstream and downstream of the reservoir, the immigrants range, and the benefits and the risk of the reservoir in a long period of the operation simulation.
