摘　　要：针对实测样本容量的局限性及方法选择等可能导致年洪水标准与分期洪水标准不一致问题,分析了年设计洪水与分期设计洪水的概率统计关系,提出了分期设计洪水组合频率与年设计洪水频率的误差估计方法及分期洪水校正方法。实例结果表明,校正后的分期设计洪水不会降低年设计洪水标准,基本符合相应分期的季节丰枯特性。As the limitations of measured series and method calibrations,seasonal flood standard may not consistent with that of annual flood.In this paper,the probability statistics relationship between annual design flood and seasonal design flood is analyzed.And then a method of error estimation between combinatorial frequency of seasonal flood and frequency of annual flood is proposed,and the correction method of seasonal flood is also given.The results of case study show that corrected seasonal design floods basically accord with characteristics of seasonal rainy and low water without lowering standard of annual design flood.
