| 摘 要： | 本文考虑到悬移质、推移质和床沙的相互交换,从沙量守恒原理出发,获得出了推移质泥沙连续方程及河床变形方程.该方程表明,推移质河床变形不仅与推移质本身不平衡输沙有关,而且还与悬移质非饱和输沙有关,推移质河床变形实质就是全沙河床变形.

On Non -Equilibrium Transport of Bed Load |
| |
| Abstract: | In this paper, Based on the theory of constant quantity of sediment transport as well as considering the interchange of the suspended load, bed load and bed material, the equations of continuation of sediment and riverbed deformation have been obtained, which show that riverbed deformation is not only related to non -equilibrium transport itself, but also to unsa -turated transport of suspended load and the deformation by the bed load in fact is due to the total sedimment. |

| Keywords: | bed load suspended load non -equilibrium transport unsatu-rated transport riverbed deformation |
