摘要
为解决原有库区一维数学模型异重流计算结果不很合理的问题,在一维模型中引入了孔口出流的概念,对浑水水库库区进行了分层计算,并探讨了小浪底浑水水库排沙的计算原理和计算方法。实例计算结果表明,采用该方法得出的出库含沙量过程基本合理。
In order to solve the problem that the density current results of the reservoir area calculated by one dimensional mathematical model was not very reasonable, orifice flow was introduced in the mathematical model and layered calculation was used for muddy water reservoir. The princi- ples and calculation methods of desilting were discussed in Xiaolangdi muddy water reservoir. The ease results show that the out flow process of sed- iment concentration in the reservoir by this method in the paper is reasonable.
