虎山水库设计洪水计算分析

Calculation and analysis of the flood design of Hushan Reservoir

虎山水库是按大型水库管理的省重点中型水库,水库流域跨河南、湖北两省交界,本文对虎山水库设计洪水进行了计算分析,通过采用图集推理公式法、淮上法和利用邻近水文站实测洪水流量资料的水文比拟法分别计算水库设计洪水。当流域面积接近多种方法的临界值时,应当采用各种方法分别计算,对成果的合理性、适应性进行多方面分析论证,最终合理选定设计洪水计算成果。

Hushan Reservoir is a provincial key medium-sized reservoir managed by a large reservoir.The reservoir basin straddles the junction of Henan and Hubei.The flood design of Hushan Reservoir is calculated and analyzed in this paper.The flood design of the reservoir is calculated respectively by adopting atlas inference formula method,Huaishang method and hydrological analogy method using measured flood flow data from adjacent hydrological stations.When the watershed area is close to the critical value of various methods,various methods should be used to calculate separately,and the rationality and adaptability of the results should be analyzed and demonstrated in many aspects,and finally the design flood calculation results should be reasonably selected.
