摘　　要：设计洪水成果的推求关系到流域水资源开发利用规划和工程设计的经济性和适用性。为掌握无实测资料山区雨源型河流的水文特性,结合抱都水库坝址以上流域特征,以威宁气象站连续降雨序列数据为依据,采用雨洪法对坝址处的设计洪水和施工分期洪水进行详细论证分析。结果表明:雨洪法推求的设计洪水成果符合山区中小型流域洪水特性,且与历史洪水调查结果一致,成果合理可信,可为工程规划设计提供详实水文数据。The derivation of flood design results is related to the economic and applicability of watershed water resources development and utilization planning and engineering design.In order to understand the hydrological characteristics of rain source rivers in mountainous areas without measured data,combined with the characteristics of the watershed above Baodu Reservoir dam site,and based on the continuous rainfall sequence data from Weining Meteorological Station,the rain flood method is used to conduct detailed analysis and demonstration of the design flood and construction stage flood at the dam site.The results show that the design flood calculated by the rain flood method conforms to the flood characteristics of small and medium-sized watersheds in mountainous areas,and is consistent with historical flood investigation results.The results are reasonable and reliable,and can provide detailed hydrological data for engineering planning and design.
