In resent years, the intrinsic properties of clays have been examined as a basic frame of reference for evaluating the effect of soil structure of natural sedimentary clays. The object of this paper is to clarify the intrinsic shear properties of clays. Shear resistance of soils are constituted of frictional component and cohesional component. In this paper, the cohesion of clay in high water content is examined in relation to the liquid limit. A number of tests measuring viscosity of clays and Vane shear tests are performed. It is shown that the shear property of clays changes at liquid limit. In lower water content than liquid limit, shear resistance obtained from viscosity test and Vane tests are in agreement with effective cohesion of clays proposed Hvorslev. It is also shown that shear property of clays in high water content is well characterized with normalized water content.
