【摘要】：随着预报科学理论和技术的发展,降雨和洪水预报精度的提高和水文过程预见期的增长,水库运用中由对水库汛限水位的静态控制逐步转向动态控制,而汛限水位动态控制的核心问题之一就是研究汛限水位动态控制域的确定方法。以岩滩水库为实例阐述了库容补偿法和预泄能力约束法的基本思想,并给出预泄能力约束法的数学描述和计算过程。通过评定岩滩水库短期洪水预报方案精度和预报误差对防洪安全的影响程度,以不增加土地淹没损失为原则,基于洪水预报信息和汛期动态控制水位调度线得出汛限水位动态控制上限值,以原设计汛限水位值为下限确定汛限水位动态控制域。
[Abstract]:With the development of forecasting theory and technology, the improvement of precision of rainfall and flood forecasting and the increase of hydrological process prediction period, the static control of reservoir flood limit water level has gradually changed to dynamic control in reservoir operation. One of the core problems of flood limit water level dynamic control is to study the determination method of flood limit water level dynamic control region. Taking the Yantan Reservoir as an example, the basic ideas of the reservoir capacity compensation method and the pre-discharge capacity constraint method are expounded, and the mathematical description and calculation process of the pre-discharge capacity constraint method are given. By evaluating the accuracy of short-term flood forecasting scheme and the degree of influence of forecast error on flood control safety of Yantan Reservoir, the principle of not increasing the loss of land submergence is taken as the principle. Based on flood forecast information and flood season dynamic control water level dispatching line, the upper limit value of flood limit water level dynamic control is obtained, and the dynamic control region of flood limit water level is determined with the original design flood limit water level value as the lower limit.
