Undrained Behavior of Compacted Sand-Clay Mixtures Under Monotonic Loading Paths

A. Shafiee, H.R. Tavakoli and M.K. Jafari

Abstract:
This study describes an experimental study on compacted sand-clay mixtures to investigate pre-failure and failure characteristics of such mixtures under monotonic compression and extension loading paths. Results reveal that pore pressure, secant modulus, undrained shear strength and angle of shearing resistance increase when sand content was raised in both compression and extension. It was also found that the tested materials were overconsolidated by the fact that normalized shear strength depends on initial confining stress. The compacted sand-clay mixtures exhibit anisotropy in mechanical behavior so that undrained shear strength and angle of shearing resistance were greater in compression than in extension. The extent of the anisotropy increases with sand content.
