1983年10月榆次会议,提出用空库排沙方案处理汾河水库泥沙问题。汾河水库是山西一座大水库,肩负着太原市防洪和工业与人民生活用水,以及汾河中、下游150万亩农田灌溉用水的艰巨任务。因此水库洩空排沙涉及面广、影响面大,必须进行充分的可行性研究。为此我们选择与汾河水库泥沙物理特性基本相同的汾河二坝进行模拟洩空冲刷试验。 October 1983 Yuci meeting, proposed empty sediment discharge program Fenhe reservoir sediment problem. Fenhe Reservoir is a large reservoir in Shanxi Province, shouldering the flood control and industrial and people’s living water in Taiyuan City, as well as the Fenhe River, 1.5 million mu of farmland irrigation water arduous task. Therefore, the discharge and sediment discharge of the reservoir involves a wide range of impacts and must be fully investigated. For this reason, we choose to simulate the venting scouring test for the second dam of Fenhe River which has the same physical characteristics as Fenhe Reservoir sediment.
