%X Particle breakage at low stress level leads to a special stress-strain relation for calcareous sand. By assuming that the strengths of particles follow a certain probability,damage parameter is obtained,then a damage bounding surface model is constructed. The relationship among particle breakage,shear expansion and confining pressure are discussed,and theory and experiment results are of good agreement.
