摘要
从悬移质运动一般扩散方程出发 ,考虑到异重流沿程不断淤积 ,含沙量不断变化 ,而且粒径沿程也不断细化 ,通过简化方程 ,推导出一维非饱和非均匀沙异重流含沙量的沿程分布方程式 .通过水槽实验资料和实测资料验证 。
Based on suspended sediment diffusion equation, and considering that the density current gradually deposits in transition, its concentration gradually varies and its grain size gradually fines; a longitudinal distribution equation of sediment concentration in unsaturated and heterogeneous density current is developed. This equation is reasonable comparing with water tank data and observed data.
