摘要
采用大型水槽高变率变态模型 ,对非恒定流用模型试验与理论分析相结合的方法 ,借汉江安康水库洪水资料来研究水库洪水传播特性。对洪水波在水库中的传播时间、入库洪水与回水末端入库洪水的关系 ,各频率设计洪水的最高库水位、下泄洪水过程、调蓄滞洪历时、洪型对水库防洪的影响等问题得出相应的结论 ,与可对比资料吻合良好。
The behaviors of floodwater transmission in reservoir are studied using the distorted model of large sized flume with high variation frequency and the method of combining the non steady flow model flow test with theoretical analysis as well as the flood data of Ankang reservoir on the Hanjiang river. Such corresponding conclusions are obtained as the transmission duration of floodwater waves in reservoir, relationships between the floodwater entering the reservoir and the backwater tail of floodwater entering the reservoir,the highest reservoir water level of the floodwater designed at each frequency,the process of floodwater discharge,the duration of regulation storage and retension of floodwater and the effect of floodwater patterns upon flood prevention problems, etc.Which are found to be in good coincidence with the comparable data. These research achievements are of great significance to the flood prevention of Ankang reservoir and the similar reservoirs.
