| 摘 要： | 通过对黄河潼关水文站的水沙条件和三门峡水库运用方式的综合分析，提出清淤时机应围绕每年的桃汛和汛期进行。通过对潼关上下游河段冲淤变化对潼关高程的影响、潼关河段的冲淤量分布、纵横向河床形态变化等技术分析，同时考虑目前的清淤规模，综合得出清淤河段首先应选在潼关至古夺断面之间。

| Abstract: | The time of clearing sediment which surround spring flood and flood season has been brought forward in this paper through analyzing condition of water-sediment at Tongguan station and operation of Sanmenxia reservoir . Through analyzing influence of erosion and deposition change in upper and lower reaches Tongguan on Tongguan elevation, distribution of erosion and deposition , change in riverbed shape etc., and meantime considering actual scale of clearing sediment, this paper puts forward that the suitable reach of clearing sediment should be chosen firstly between Tongguan and Guduo. |
