Stress–strain relations of cement-mixed gravelly soil from multiple-step triaxial compression test results

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

A Constitutive Relationship for Gravelly Soil Considering Fine Particle Suffusion

Suffusion erosion may occur in sandy gravel dam foundations that use suspended cutoff walls. This erosion causes a loss of fine particles, degrades the soil strength and deformation moduli, and adversely impacts the cutoff walls of the dam foundation, as well as the overlying dam body. A comprehensive evaluation of these effects requires models that quantitatively describe the effects of fine p...

Characterization of Soil-water Retention of a Very Gravelly Loam Soil Varied with Determination Method

Soil-water characteristic curves were determined for Krome calcareous very gravelly loam soil in the laboratory and in situ in an orchard. In the laboratory, soil-water retention was determined with a pressure plate and pressure Tempe cells for soil collected from vegetable fields. In the orchard, soil-water suction measured with tensiometers was compared to volumetric soil-water content (E) de...

Curing Time Effect on Behavior of Cement Treated Marine Clay

Cement stabilization has been widely used for improving the strength and stiffness of soft clayey soils. Cement treated soil specimens used to investigate the stress-strain behaviour in the laboratory study are usually cured for 7 days. This paper examines the effects of curing time on the strength and stress strain behaviour of cement treated marine clay under triaxial loading condition. Labor...

Numerical Investigation on the Reference Crushing Stress of Granular Materials in Triaxial Compression Test

Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...
