某水库设计洪水参数分析计算

Analysis and Calculation of Design Flood Parameters of a Reservoir

尹武水库行政区划属昭通市巧家县老店镇尹武村,坝址位于牛栏江左支流老店河的源头河流尹武沟上,属金沙江水系。洪水参数的合理性对工程投资、安全具有较大的影响。水利工程设计前,确定科学、合理的设计洪水参数是十分必要的。通过收集尹武水库流域多年水文参数,选取多种方法计算水库设计洪水参数。从安全方面考虑,选取暴雨洪水法计算结果作为设计洪水成果。通过合理性分析,推荐成果与昭通地区分布规律基本一致,设计洪水参数成果较为合理。

Yinwu Reservoir administrative territorial entity is located in Yinwu village, Laodian town, Qiaojia County, Zhaotong. The dam site is located on Yinwu ditch, the source river of Laodian River, the left branch of Niulan River, which belongs to Jinsha River River system. The rationality of flood parameters has great influence on project investment and safety. Therefore, it is necessary to determine scientific and reasonable design flood parameters before hydraulic engineering design. Through collecting the hydrological parameters of Yinwu reservoir basin for many years, many methods are chosen to calculate the design flood parameters of the reservoir. Considering the safety, the calculation result of storm flood method is selected as the result of design flood. Through the rationality analysis, the recommended results are basically consistent with the distribution law of Zhaotong area, and the result of design flood parameters is more reasonable.
