摘要
在介绍立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、推导了立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 standing wave, a theoretical solution of bottom shear stress due to standing wave action was derived by assuming the water to be viscous fluid and the mud to be visco elastic medium. And the relationship between critical bottom shear stress and rheology parameter of bottom mud was obtained in laboratory experiments.
