设计洪水频率曲线参数的估算与确定

Talking on Estimating and Ascertaining Parameters of Design Flood Frequency Curve

本文通过阐述设计洪水频率曲线 (目估适线法 ) ,由矩法估计的参数存在着系统的计算误差 ,利用概率论基本论点 ,通过工作中的实例 ,说明采用矩法估计出频率曲线参数 (均值与Cv值 )的初始值 ,应进行合理的调整。

This paper represents design frequency curve, in which the parameter calculated by the matrix method exists the systemic error . The initial value of the parameter estimated by the matrix way should be reasonably regulated using the basic probability theory in order to make it approach practical project.
