摘　　要：针对水利工程设计中用分时段同频率放大法推求设计洪水的不足,提出一种通过解线性方程组推求设计洪水过程线的简便方法。该方法运算过程简单,直接利用Excel的内置函数求解,又能避免徒手修匀洪水过程线的任意性。文中给出了一个计算实例。To overcome the shortages of the method that enlarges the model hydrograph by keeping the peak discharge and flood volume of different duration in the same frequency, this paper gives a method for calculating design flood hydrograph through solving a system of linear equations. This method reduced the arbitrariness caused by man-made work. An applied example is also given in this paper. Keywords：
