There are various discontinuities in the rock mass, they make physical and mechanical properties of rock mass become very complicated and play a controlling role in Engineering rock deformation and stability, so the research of discontinuity is an important part in the rock mechanics and engineering geology. Carrying out simulation about stress and deformation process of inerratic and serrated discontinuity based on theories about discontinuities and FLAC3D. Conclusions include:stress of rock mass increase with normal stress increase,horizontal deformation of rock mass reduced with normal stress increase before damage of rock mass, but horizontal and vertical deformation increased rapidly after damage of rock mass; shear stress and shear displacement of discontinuities increase with vertical stress increase, the speed of increase is accelerated particularly after damage of rock mass, location of maximum shear stress and shear displacement change; the up and downs angle is inverse proportion to the stress and deformation, it is in proportion to the shear strength of rock mass.
