Abstract

The flow properties of marine clays, the water content of which are much larger than the liquid limit are studied experimentally. A series of vane shear tests and rotary viscometer tests were carried out with four marine clays with different water contents larger than the liquid limit. It was found that the yield stresses obtained by the viscometer were closely related with the water contents normalized by liquid limit. Using water content normalized by the liquid limit, a unique relationship between shear stress and shear rate is obtained. As a result, it was known that the flow properties of marine clays with high water content can be estimated by knowing the normalized water content or vane shear strength. These findings are useful to consider the wave-mud interaction problem.
