Abstract基于宾汉模型,并运用量级分析方法建立了长波、水流作用下浮泥运动简化方程。简化后的浮泥运动方程是一个非线性的常微分方程。运用解析与数值混合的方法进行求解,计算量很小。讨论了水流对泥面的剪应力、波幅、波长、浮泥层厚度以及浮泥密度等多组参数对浮泥输运速度的影响。研究表明,存在波浪的情况下,即使水流对泥面的剪应力远小于浮泥屈服应力浮泥也能出现定向的输运。
Other AbstractIn this paper, Bingham-Plastic model is employed to give the relation between stress and strain,and simplified equations of fluid mud motion under long wave and current are presented by order analysis. The simplified equations are non-linear ordinary differential equations which can be solved by hybrid Numerical-Analytical technique. And the computational coat is very low. The effects of the shear stress acting on the fluid mud bed,wave amplitude,wave-length,the depth of fluid mud layer and bulk density of fluid mud on the fluid mud transportation are discussed. Under the condition of wave and current coexistence, the fluid mud can move toward one direction even if the shear stress acting on the fluid mud bed is smaller than fluid mud yield stress.
