摘要
为研究特大值处理对频率计算结果的影响,通过对官寨水文站实测资料进行频率计算,对其中一次较大洪水的考虑,采用了不同方法进行处理,再运用皮尔逊Ⅲ型曲线进行配线,得到设计频率下的设计洪水值,并对所得结果进行对比分析,以说明较大洪水视为特大洪水与否对工程设计的影响,从而给水文工程设计者提供较为合理的建议。
Trough frequency computing based on the survey data of Guanzai gauge station, and considering a larger flood, using different treatment measure and Pearson Ⅲ curve, the design flood value is gotten in design frequency, the calculating results are compared and analyzed. Tt illustrates if treating the larger Flood as catastrophic flood and if impacting engineering design, and provides more reasonable hydrological and engineering recommendations for designers.
