The undrained shear strength characteristics of silty sand : an experimental study of the eff ect of fi nes
This laboratory investigation has been conducted to elucidate how the fi nes fraction affects the undrained residual shear strength and liquefaction potential of sand-silt mixtures (Algeria). A series of monotonic and cyclic undrained triaxial tests were carried out on undrained, reconstituted, saturated samples of sand with varying fi nes content ranging from 0 to 50%. These were undertaken in...
متن کاملTheoretical Undrained Shear Behaviour of Unsaturated Soils
Prediction method for undrained shear behaviour of unsaturated soils is discussed in this paper. Based on Original Cam Clay model, authors have proposed constitutive model for unsaturated soils that the effect of water content is incorporated into superloading surface concept. Firstly, stress path of constant volume shear test is formulated under constant void ratio condition. And relationship ...
متن کاملStudies 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...
متن کاملStability of Undrained Deformation of Fluid-saturated Geo-materials
The presence of pore fluids in geomaterials can alter deformation processes and facilitate or delay material failure. Dilation/contraction of geomaterials in the course of inelastic undrained deformation causes a reduction/increase in pore pressure altering the effective compressive stress. This results in an increase/decrease in shear stress that can be sustained by the material over the corre...
متن کاملevaluation of undrained shear strength of loose silty sands using cpt results
series of undrained monotonic triaxial tests and cone penetration tests were conducted on loose silty sand samples to study correlation between undrained shear strength of silty sands (sus) and piezocone test results. cpt tests were conducted at 27 silty sand samples in calibration chamber. the results indicate that, in low percent of silt (0-30%), as the silt content increases, the undrained s...
