穿黄渡槽长度是渡槽设计中极其重要的指标，对工程量和投资影响极大。本文结合穿黄河段的实际情况，根据黄河下游实测资料分析、动床物理模型试验、数学模型计算等方面的成果，分析研究了穿黄渡槽缩窄河道后对穿黄河段洪水演进、泥沙冲淤及河势等可能产生的影响，并进行了槽孔水力计算。在此基础上，经综合比较，确定孤柏嘴穿黄波相长度为3500m，既满足了黄河行洪排沙的要求，又节减了穿黄渡槽的工程量和投资。
The length of the Yellow Aqueduct is an extremely important indicator of aqueduct design, which has a great impact on the project volume and investment. Based on the actual situation of the Yellow River section, this paper analyzes the research results of the Huanghe River fluvial process, the sediment flushing Siltation and river potential and other possible effects, and carried out slot hydraulic calculation. On this basis, after a comprehensive comparison, it is determined that the length of the yellow wave phase of Guber mouth is 3500m, which not only meets the requirements of flood and sediment discharge of the Yellow River but also reduces the project volume and investment in the Yellow River aqueduct.
