【Abstract】 Under tension and shear conditions related to unloading of rock mass,the linear elastic fracture mechanical model is established. According to the model,the equations of stresses,strains and displacements of the region relatively far away from the crack(the distance between the research area and the central point of crack is two times larger than the length of the crack) are derived.Computational results of those equations are compared with observational data of unloading testing.更多还原
