为提高百色水库对洪水的调节作用和洪水资源化利用效益,对百色水库进行分期汛限水位动态控制。先对百色水库进行汛期分期,计算各分期设计洪水;然后,采用老口水库与百色水库洪水同频、区间洪水按实际典型组成分配及老口水库与区间洪水同频、百色水库洪水按实际典型组成分配两种工况,分析了主汛期、汛末期南宁市洪水地区组成;最后,针对百色水库主汛期和汛末期不同汛限水位,对百色、老口水库进行联合洪水调度,得到百色水库主汛期汛限水位调整域为214~215 m;汛末期汛限水位调整域为214~223 m。由此可知,对百色水库进行汛限水位动态控制可提高洪水资源化利用效益。
In order to improve the regulation effect of Baise Reservoir on floods and the utilization efficiency of flood resources, the Baise Reservoir was dynamically controlled by the flood control water level. First, the Baise reservoir flood season staging to calculate the design flood of each staging; then, using the old mouth reservoir and Baise reservoir flood with the same interval flood according to the actual typical composition and the old mouth reservoir and interval flood frequency, Baise reservoir flood according to the actual typical Composition distribution of two conditions, analysis of the main flood season, the flood season in Nanning City at the end of the flood; Finally, according to the main flood season and the end of the flood season Baise different flood control level, Baise, Laokou reservoir joint flood control, Baise reservoir The flood control water level adjustment range is 214-215 m, while the flood control water level adjustment range is 214-223 m at the end of flood season. It can be seen that the Baise reservoir flood control water level dynamic control can improve the utilization of flood resources.
