文章对小浪底水库支流河口淤积变化特性进行了分析,从理论和实测数据分析反映,小浪底水库在没有完成拦沙淤积库容前,受水库运行方式的影响,主河道出现明显刷槽几率不大,干流主要以淤积粗沙为主,支流河口形成明显拦门沙坎的条件不具备。小浪底库区支流淤积以异重流倒灌淤积为主,在目前不具备采用工程措施的条件下,调节水沙关系,利用支流拦沙库容淤积粗沙是延长小浪底拦沙库容使用年限的重要途径之一。
Based on the analysis of theoretical and measured data, the Xiaolangdi Reservoir is affected by the operation mode of the reservoir before sediment storage is completed. There is not obvious obvious brushing groove in the main channel, The main siltation coarse sand-based, tributary estuary formed a clear barrier to sand ridge conditions do not have. Xiaolangdi reservoir tributaries siltation with different heavy-flow intrusion siltation-based, in the current does not have the use of engineering measures to adjust the relationship between water and sediment, the use of tributary sediment storage capacity of sediment is an important way to extend Xiaolangdi sediment storage capacity of life one.
