The Effect of Particle Breakage of Calcareous Sand on Shear Strength Using a Stress-Dilatancy Model
Calcareous sediments are distributed approximately 40% of the world’s seafloor. Previous research on calcareous soils generally recognizes that these soils demand special consideration due to their unique characteristics such as high carbonate content and porous particle structures. Calcareous sands can experience dramatic particle damage during driving, resulting in excessive foundation settlement. Particle breakage has been considered as the most effective parameter to describe its physical behavior. To evaluate the effect of particle breakage on shear strength, triaxial consolidated drained tests were performed on calcareous sand with varying percentages of crushed material at various confining stresses. The particle size distribution of calcareous sand was determined before and after each test to check the relative particle breakage. A modified stress-dilatancy model is used in this study to investigate the correlation between the effective stress ratio, dilatancy, and particle breakage of the tested soils.
