【摘要】：在收集整理与故县水库大坝中孔运用相关资料、分析故县水库原设计情况的基础上,按中下游水库群现状和小浪底水库正常运用期两种情况,进行黄河中下游水库群前汛期联合防洪调度计算及后汛期故县水库单库调洪计算,分析故县水库前、后汛期大坝中孔退出防洪运用对故县水库、洛河下游及黄河下游防洪的影响。故县水库大坝中孔退出防洪运用,前汛期故县水库20 a一遇洪水最高水位为543.20 m,未超过移民水位544.20 m;万年一遇洪水最高水位为549.66 m,未超过551.02 m的设计指标。花园口站洪峰流量最大变幅为100 m~3/s,10 000 m~3/s以上洪水洪量最大变幅为0.32亿m~3,对东平湖和北金堤滞洪区的运用标准基本无影响。后汛期故县水库大坝中孔退出防洪运用方案对故县水库设计洪水位、校核洪水位等特征水位基本无影响。
[Abstract]:Based on the collection and arrangement and the application of the relevant data in the reservoir of the reservoir of the old county, the present situation of the reservoir in the middle and lower reaches and the normal operation period of the Xiaolangdi Reservoir are analyzed on the basis of the analysis of the original design of the reservoir in the county. The calculation of flood control and flood control in the middle and lower reaches of the Yellow River before and after the flood season and the flood control of the reservoir in the old county of the flood season are calculated, and the effect of the application of the flood control on the flood control of the reservoir, the downstream of the Luohe and the downstream of the Yellow River is analyzed before and after the reservoir in the county. The flood control and application of the middle hole of the dam in the old county of the county, the maximum flood level of the reservoir in the first flood season of the reservoir in the first flood season is 543.20m, and the flood level is not more than 544.20m; the highest water level of the flood in the year of the year is 549.66m, and the design index of not more than 551.02 m is not exceeded. The maximum amplitude of the flood peak at the garden port station is 100 m ~ 3/ s, and the maximum variation of the flood volume between 10 000 m ~ 3/ s and above is 0.32 billion m ~ 3, which has no effect on the application standard of the Hongfeng District in Dongping Lake and Beijin Dike. After the flood season, the flood control application program of the middle hole of the dam in the reservoir of the county reservoir has no effect on the design flood level and the check flood level of the reservoir in the old county.
