Abstract A set of saturated and dry-saturated large-scale triaxial tests were conducted in order to explore the effects of stress conditions on the saturation-induced collapse deformation behavior of a rockfill material. Specimens were tested in different confining pressures and for dry-saturated tests the specimens were submerged in various shear stress levels. The results indicate that in all of the dry-saturated tests a sudden reduction in the volume of the specimens was observed during the submerging process. The ratio of the minimum axial strength of a submerged specimen (at the end of the saturation process) to the shear strength of the specimen before saturation is defined as the coefficient of stress recovery, C sr . Results of the dry-saturated tests showed that this ratio increases as the confining pressure increases and decreases by increasing the shear stress level. According to the results of dry-saturated tests the values of internal friction angle reduction caused by saturation (Δϕ c ), the ratio of the elasticity modulus of the material after saturation to its elasticity modulus in dry condition, i.e., E wet /E dry , and also the saturation induced sudden volumetric strain (ε vc ) decrease as the confining pressure increases. However the shear stress level does not have any meaningful effect on the variation of Df c , E wet /E dry and (ε vc ).
