【Abstract】 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.更多还原
