悬移质不平衡输沙水流挟沙能力

The carrying Capacity on the Non—equlibrium Transportation of Suspended Load

本文从悬移质挟沙能力的基本概念出发,推导出悬移质非均匀沙平衡输沙的挟沙能力及不平衡输沙的挟沙能力公式,这些公式进一步揭示了非均匀沙的输沙机理,全面地描述了各种河床组成在不同的来水来沙条件下的输沙规律,适用性广,计算简便。

Based on the basic conception of the carrying capacity of suspended load, the formulas of equilibrium and non-equilibrium transportion for nonuniform suspended sediment are derived. The charateristics of the formulas are as follows: a. The mechanisms of equilibrium and non-equilibrium transportation of nonuniform sediment are further clarified; b. The transporting law of suspended load is described under various bed material and incoming flow and sediment conditions; c. The formulas are easy to be applied and used widely.
