SHEAR CHARACTERISTICS OF SATURATED GRAVELLY CLAYS

Studies on Dynamic Character of Saturated Soft Clays through Cyclic Torsion Shear Tests

A large number of cyclic torsional shear tests on saturated soft clay under unconsolidated undrained condition have been carried out. The changing law between accumulative generalized shear strains vs. failure numbers has been analyzed and a cyclic shear strength curve has been received based on cyclic torsional shear tests. According to the test results, the criterion of saturated soft clay is...

Prediction of Consolidation Properties of Partially Saturated Clays

Consolidation properties of soil are essential for prediction of the deformation characteristics, determination of which involves considerable time, cost, and rigorous testing process. Further, natural state of saturation is not simulated and thus for partially saturated soils the standard odometer test gives misleading results of the evaluated consolidation parameters particularly the overcons...

Shear Viscosity of Clays to Compute Viscous Resistance

Soils at critical state are like a visco-plastic fluids, which will flow for applied stresses greater than the critical state (CS) shear strength. Shear viscosity is a key parameter to understand the post-failure flow response of soils in geotechnical applications such as landslides, jacked piles and cone penetrometers. Viscosity of soil has been investigated for water contents greater than the...
