Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

This paper describes triaxial compression tests conducted to determine the effect of fiber inclusion on stiffness and deformation characteristics of sand-gravel mixtures. Tested soil was a mixture of Babolsar sand from the shores of the Caspian Sea and Karaj River gravel. Portland cement was used as the cementing agent and fibers 12mm in length and 0.023mm in diameter at 0%, 0.5% and 1.0% were ...

Abstract A number of discrete element analyses undrained triaxial shear tests on crushable assemblies are performed using 3-dimensional particle flow code (PFC3D). The the samples is simulated by assigning different velocities at boundaries to control constant volume during shear. Particle breakage studied octahedral stress criterion and fragment spawning mode satisfying an Apollonian sphere pa...
