摘　　要：忠太水库位于滇西北缺资料的双雨季地区,其设计径流计算是工程的重难点之一。本文基于邻近水文站的水文特性推断出忠太水库流域年内降雨虽为双峰但径流分配为单峰特征;用水文比拟法(上桥头、阿东为参证站)和等值线图法计算的设计年径流,上桥头比拟的年径流最小;以单汛期、双汛期两种年内径流分配模式进行兴利调节计算的结果,单汛期所需的兴利库容更大,从对工程不利的角度应选择单汛期的上桥头为参证站计算设计年径流和年内径流分配。计算方法可为类似双雨季地区设计径流计算提供参考。Zhongtai Reservoir is located in the double rainy season area of northwest Yunnan,and its design runoff calculation is one of the most difficult points in the project.Based on the hydrological characteristics of adjacent hydrological stations,this paper infers that although the annual rainfall in Zhongtai Reservoir basin is bimodal,the runoff distribution is unimodal.Hydrological analogy method(Shangqiaotouarea and Edong are the reference stations)and contour map method are used to calculate the design annual runoff,and the annual runoff compared with Shangqiaotou area is the smallest.According to the annual runoff distribution model of single flood season and double flood season,the profit-making capacity required in single flood season is larger.From the unfavorable point of view of the project,Shangqiaotou area in single flood season should be selected as the reference station to calculate the designed annual runoff and annual runoff distribution.Calculation method can provide references for other double rain season areas to calculate runoff design.
