针对采用《宁夏暴雨洪水图集》计算设计洪水、计算成果与典型实测暴雨洪水频率关系进行分析,认为宁夏地区洪峰与洪量的发生频率有一定的相关关系,但相关性较差。洪峰与洪量不同频的现象较多,与设计条件认为是同频率的暴雨产生同频率的洪水有一定的差异。

Ningxia arid regions adopt the atlas of Ningxia storm floods to calculate the design flood,this paper analyses the relationship between calculation result and typical measured storm floods frequency ,there is a poor correlation between the frequency of flood peak and flood volume. The phenomenon of flood peak and flood volume with different frequency is more,there is a difference in the design condition that flood peak and flood volume with same frequency.
