| 摘 要： | 利用建立的平面二维非恒定水流泥沙数学模型,在上游来流为10000年一遇的特大洪水过程情况下,就初步拟定的南水北调中线穿黄方案之一的孤柏嘴线路3 0km隧洞工程方案,穿黄隧洞束窄河道对河段水流流态、泥沙运动及河床变形的影响进行了计算和分析比较。计算结果表明,在该洪水过程情况下,穿黄隧洞束窄河道对河段水沙运动特性有一定影响,但影响不大。

| Abstract: | The tunnel is one of the ways to cross the Yellow River in South Water to North Project.This paper has calculated and analyzed the influence of the project on the flood flow,sediment movement and river bed deformation,which is only referred to the tunnel method,using the 2D-horizontal unsteady numerical model and in the flood process once per 10000 years.It has been proved that there is little influence of the tunnel on flow and sediment movement in the flood process. |
