THE SHEAR STRENGTH OF UNSATURATED SOILS

The shear strength of an unsaturated soil is written in terms of two independent stress state variables which show the transition from a saturated to an unsaturated state. The independent roles of changes in total stress and changes in pore-water pressure are easily visualized in the formulae. The limited data provided by published research literature substantiate that the shear strength can be described by a planar surface of the forms proposed. A procedure is also outlined to evaluate the pertinent shear strength parameters from laboratory test results. (TRRL)
