Abstract The unloading tests on rock samples under different confining pressures were carried out on the system MTS815 to study the deformation and energy characteristics of quartz mica schist with horizontal and vertical foliation respectively. The volume deformation coefficient，the energy ratio，the energy change rate and the energy stress increment ratio were analyzed to investigate the mechanism of energy evolution and deformation failure characteristics of quartz mica schist under the unloading of high confining pressure. The results show that both the radial deformation capacity and the values of characteristic stresses of the sample with the horizontal foliation are higher than those with the vertical foliation. The confining pressure has the obvious influences on the energy evolution of both type of samples. The pre-peak energy stress increment ratios of both groups increase with the initial confining pressure，however the post-peak energy stress increment ratios are almost unaffected by the initial confining pressure.

Key words： rock mechanics mica-quartz schist characteristics of transverse-isotropic unloading deformation failure energy evolution
