【摘要】：以浦阳江为研究背景,选择浦阳江1999年6月17-19日作为研究时段,通过建立二维水动力模型,探讨了浦阳江尖瘦型洪水过程中高湖不同泄洪总量和泄洪方式作用对浦阳江沿程洪水位的影响。研究结果表明:在上游进口~湄池河段,3种泄洪方式作用下洪峰水位均随着高湖泄洪总量的增大而降低,且"先增后减"泄洪方式的洪峰水位均最低。当高湖泄洪总量大于1 500万m3时,洪水第二日"先增后减"泄洪方式以及洪水第三日"均匀变化"泄洪方式作用下洪水位曲线均位于其他两种泄洪方式的下方,且间距均随泄洪总量的增大而增大。而在浦阳江下游的临浦,高湖泄洪总量与不同泄洪方式组合对洪水位曲线变化规律、洪峰水位值以及洪峰到达时间无影响。研究结论可为优化高湖泄洪闸的调控方式提供指导。
[Abstract]:Taking Puyang River as the research background, this paper chooses Puyang River as the research period from 17 to 19 June 1999, and establishes a two-dimensional hydrodynamic model. The effect of different flood discharge amount and flood discharge mode on flood level along Puyang River during thin flood of Puyang River is discussed. The results show that Hong Feng is under the action of three kinds of flood discharge modes in upstream entrance to Meanchi reach. The water level decreases with the increase of the total amount of flood discharge in the high lake. Hong Feng's water level is the lowest in the "increase first and then decrease" flood discharge mode. When the total flood discharge amount of the high lake is more than 15 million m ~ 3, The flood level curve under the action of "increase first and then decrease" on 2nd and "uniform variation" in 3rd is below the other two flood discharge modes. The spacing increases with the increase of the total amount of flood discharge, while in the lower reaches of Puyang River, the total amount of flood discharge and the combination of different flood discharge modes affect the variation law of flood water level curve in the lower reaches of Puyang River. The water level of Hong Feng and the arrival time of Hong Feng have no influence. The conclusion of the study can provide guidance for optimizing the regulation mode of flood sluice in Gao Lake.
