摘要
在无实测径流资料的地区,水电工程径流分析计算主要通过参证站与设计断面的集水面积缩放方法来推求,其关键就在于如何根据实际情况选择合适的设计参证站。以鲜水河支流甲斯孔流域的规划梯级电站工程径流分析计算作为典型例子,通过参证站、对比参证站及水文手册3种方法计算的参证站选择及径流成果合理性分析,提出了无资料地区设计参证站选择的一些建议。
In un-gauged region,the runoff analysis and calculation method about hydraulic power station engineering mainly use the reference station and the catchments area of the design section＇s ratio to get,and the key is how to choose the appropriate design station with the practical project.This paper use the cascade hydropower station＇s runoff calculation xianshui river＇s streams Jiasikong basin as typical example,through the reference station and contrast reference station and hydrological manual three methods to calculate the runoff,and through analyzing the result come up with some advises of how to choose the design reference station in the un-gauged region.
