推进波作用下的底泥起动

Threshhold movement of bottom mud due to progressive wave action

摘要: 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。

Abstract: Based on the properties of the threshold movement of bottom mud due to progressive wave, a theoretical solution of bottom shear stress due to progressive wave action was derived, assuming the water as viscous fluid and the mud as visco-elastic medium. And the relationship between critical bottom shear stress and rheology parameter of bottom mud was obtained in laboratory experiments.
