在介绍推进波作用下底泥起动特点的基础上 ,将上层水体作为粘性流体、底泥作为粘弹性体 ,推导了推进波作用下泥床面剪应力的表达式 .并根据试验结果 ,给出了推进波作用下底泥起动时的床面剪应力与底泥流变参数的关系
Based on the characteristics of sediment initiation under the action of propulsive wave, the expression of shear stress on the bed surface under the action of propulsive wave is deduced by using the upper water body as the viscous fluid and the sediment as the viscoelastic body. Based on the experimental results, The relationship between the bed shear stress and sediment rheological parameters at the start of sediment under propulsion wave action
