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 。
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.
