根据各种经验公式及沿程水头损失的计算理论,初步计算了小浪底水库自吸式管道排沙系统的管道临界不淤流速及沿程水头损失.结果表明,在汛限水位下,当主管道铺设高程为145m时,清淤的距离可达坝前24710m,基本可以将小浪底坝前20km库区范围、高程145～175m的细泥沙排出库外.

分析了小浪底库区管道排沙大范围清淤、高强度输沙清淤及坝前小范围清淤等三种主要方式,认为:坝前小范围清淤方式技术难度低、可行性高,可以长期保持坝前5km内不产生泥沙淤积;合理地进行系统操作,提高管道排沙系统效率,将会进一步降低清淤单价.
为了解决蓄水与水库淤积的矛盾,设计了在库区淤泥清除管道系统上使用的水库自吸式排沙管道吸泥头吸泥浓度控制装置.结果表明,通过控制管道入口与浆体液面的位置关系,在管道排沙运行时可准确、稳定地控制管道泥沙浓度,从而使排沙管道系统安全、高效地运行.
对小浪底水库自吸式管道排沙系统的管道材料选取、管道连接方式、铺设施工工艺和管道过坝施工技术等进行了研究,认为U-PVC缠绕管材可满足排沙管道要求,在日前的设备技术条件下,管道施工有成熟的实施条件.同时,对管道铺设方式和与过坝隧洞连接等施工关键问题提出了相应的解决方法.

黄河小浪底水利枢纽作为黄河下游水沙控制的关键部位,对其泥沙淤积情况观察至关重要.常规水文观测表明坝前淤积主要为细泥沙,而采用黄科院研制的深层取样设备检测结果表明,小浪底坝前存在一定厚度的中沙和粗沙.常规水文观测取样器和深层取样器在垂向取样位置不同,河床表层和深层淤积泥沙的检测结果差异很大.
