WebApr 4, 2015 · An equation for the dilatancy angle is proposed that requires only two unit-independent soil constants, which can be obtained by conducting triaxial or plane strain tests. WebThe general stress-dilatancy relationship obtained from the frictional state concept, with some additional assumptions, gives the possibility of finding theoretical relationships between the friction angle of sand at triaxial compression and triaxial extension and plane strain conditions. WebJul 7, 2013 · Abstract The paper presents diagrams of the (1) drained and undrained effective stress friction angles of sand; (2) dilatancy angle of sand; (3) parameters in a nonlinear constrained modulus expression for virgin loading, unloading, and reloading on sand and silt; and (4) diagrams with the coefficient of permeability for sand, silt, and clay. check printhead
