初步探讨清江隔河岩电站水库雨洪基本关系,分析表明,在清江流域各种情况下雨洪关系均十分密切。通过对46次达标洪水普查分析,雨洪时间差大都在1～2天,致洪降水的影响天气系统最明显的是700hPa切变线。分析还得出,隔河岩电站水量利用率可达90%以上。文中揭示的事实对隔河岩电站水库调度是有益的。 Preliminary study on the basic relationship between reservoir flood and flood at Geheyan Hydropower Station in Qingjiang River shows that there is a close relationship between flood and flood under various conditions in Qingjiang River Basin. Through the 46 times the standard flood census analysis, most of the rainstorm time difference between 1 and 2 days, the impact of floods on the weather system is the most obvious 700hPa shear line. The analysis also shows that Geheyan hydropower station water utilization rate can reach more than 90%. The facts disclosed in this paper are beneficial to the Geheyan hydropower station reservoir operation.
