Abstract Take the interlayered rock mass composed of green schist and marble as subject of study，the numerical analysis of its mechancial characteristics under unloading condition was done by using FLAC3D. The research results show that the initial deviatoric stress has great effect on stress state and deformation when rock sample fails of confining pressure reduction test under constant axial stress. The stress increment ratio also has great effect on stress state and deformation when rock sample fails of confining pressure reduction test with increasing axial stress. The stress path has little effect on characteristics of strength and deformation of rock. The strength of interlayered rock mass is nearly not influenced by the stress path，but the deformation is significantly affected.

Key words： rock mechanics interlayered rock mass unloading characteristics of strength characteristics of deformation
