摘要
水流输沙相似是悬沙模型必须满足的基本条件。众所周知 ,目前所流行的所谓沉降和悬浮相似条件在变态模型中互为矛盾。理论分析表明 ,在变态模型中该两个相似条件均不能成立 ,替代它们的是一个所谓垂向泥沙通量比相似条件。
Sediment transport similarity is a postulate for model of suspended load.Similar conditions of deposition and suspension for distorted model are incompatible and from theoretical analysis,it is demonstrated that both of the above two similar conditions are not tenable,and a similar condition of vertical sediment flux ratio is presented as a substitute.In this way,the simlar conditions of the suspended load transport and the riverbed deformation are tenable.
