SOIL SHEAR STRENGTH

The vane device offers a simple means for taking shear strength measurements of weak or sensitive clayey soils. So the engineer could better determine how to interpret the test data, this study was undertaken to clarify the influence of testing variables and of in-situ stress and strain conditions on vane shear strength data. The data clearly showed that the measured shear strength of a clay soil is dependent on the test speed. This dependence is probably a function of two independent variables--effective stresses and shear strength properties of the soil.
