摘　　要：三峡水库试验性蓄水以来的调度运行实践表明,汛期对中小洪水实施滞洪调度,既减轻长江中下游防洪压力,又提升了三峡水库洪水资源利用水平。为了提升三峡水库洪水资源利用水平,针对30 000~55 000m3/s的水库来水进行了洪水资源利用研究。通过研究,提出了洪水资源利用的基本原则和控制条件,分析了洪水资源利用启动时机和预报预泄条件,制定了三峡水库洪水资源利用调度规则,分析了洪水资源利用的防洪影响和发电效益。同时考虑到洪水预报误差、预见期、上游水库调蓄作用的影响,开展了2012年洪水资源利用实例分析。研究还定量明确了三峡水库洪水资源利用的调度方式和效益分析,研究结果对于发挥三峡水库综合利用效益具有重要的理论意义和良好的推广应用价值。The scheduling operation practices since the trial water impoundment of the Three Gorges Reservoir show that,implementing schedule for medium and small-sized floods during flood season not only release the flood control pressure to the lower reaches,but also improve flood utilization level of TGR. To promote the utilization of flood resources,a comprehensive research was conducted on the utilization scheduling of flood resources for inflows between 30000 ~ 55000 m3/s in 2012. Firstly,the basic principles and control conditions of flood resources utilization were studied; then the starting time and the pre-discharge conditions were analyzed; next,the scheduling rules were formulated and its impact on the flood control and generation were analyzed. Finally,by considering the influences of flood forecasting errors,forecasting period and the regulation effect of upstream reservoirs,we carry out a case analysis for the TGR in 2012. The study quantifies the scheduling and benefit of flood resources utilization of TGR.
