An equation is presented which was developed for determining the shear strength of predominantly sandy soils and sands using the vane shear test: Torque T=Cx (cohesion factor) + Px (friction factor). The mathematical derivation of the cohesive factor and of the friction factor are set forth. It has been shown that whereas in the case of clays, the surface of resistance is a cylinder of dimensions equal to the height and diameter of the vane, in the case of sands and sandy soils, dimensions of the surface of resistance are functions of the angle of internal friction of the soil. Based on this, a relationship was derived between the torque and the angle of internal friction and cohesion. Agreement has been excellent when laboratory results obtained with the vane shear test on sand, sandy soil, clay and cinder are compared with the results of triaxial and direct shear tests.
