小浪底水库运用后三门峡水库运用方式中一些问题的初步研究

Preliminary Study on Operation Mode of Sanmenxia Reservoir after Xiaolangdi Project Operated

小浪底水库投入运用后三门峡水库的运用方式将作调整，本文运用黄河水库一维水动力学泥沙数学模型通过典型条件下的方案对比计算与分析，从减少库区淤积及增加电站出力两方面综合考虑，认为水库非汛期运用的第４方案较好；从排沙效果来看，汛期水库降低水位开始排沙的入库流量应选择大于１５００ｍ３／ｓ为宜。

The operation mode of Sanmenxia reservoir should be adjusted after Xiaolangdi project impounded. In this paper, some schemes are drawn up. These schemes are calculated by established one dimensional sediment mathematical model. Two recommended modes are given according to the computational results and the field data.
