设计洪水分析是抽水蓄能电站工程设计的关键内容之一,以垣曲抽水蓄能电站为例,根据我国现行设计洪水理论,利用相关水文资料,结合历史调查洪水成果,分别采用水文比拟法、瞬时单位线法、推理公式法、经验公式法计算该电站坝址设计洪水,综合比较最终选择水文比拟法作为设计洪水结果,并利用地区综合法进行合理性检验。结果表明,垣曲抽水蓄能电站设计洪水符合区域暴雨洪水特性,研究结果可为山西省小流域设计洪水分析提供重要参考价值。 Design flood analysis is one of the key contents of engineering design of pumped-storage power station. Taking Yuanqu Pumped Storage Power Station as an example, according to the current design flood theory in our country, using relevant hydrological data and historical investigation flood results, Instantaneous unit line method, inferential formula method and empirical formula method to calculate the design flood of the power station dam site, and to compare the final selected hydrological simulation method as the design flood result, and to test the rationality by using the regional comprehensive method. The results show that the design flood of Yuanqu Pumped Storage Power Station accords with the characteristics of regional storm flood, and the research results can provide important reference value for the design flood analysis of small watershed in Shanxi Province.
