UNDRAINED SHEAR STRENGTH OF UNSATURATED SOILS
by.genie.uottawa.cacompressive strength, cu, for field specimens obtained from various depths. While this assumption is somewhat realistic for saturated soils, its usage is questionable for interpreting the undrained shear strength of unsaturated soils. The independent contribution of matric suction towards the undrained shear strength is generally
