In order to study the axial and radial creep characteristics of rock post-peak, creep test of red sandstone post-peak under uniaxial compression was carried out to obtain the axial and radial creep curves of different states of rock post-peak, the axial and radial creep features of rock post-peak were discussed ,by using MTS815 rock mechanics test system, the influence regular pattern of the damage degree was researched, and confining pressure increment on the axial and radial creep characteristics of rock post-peak were discussed. The experimental results show that the axial and radial creep curves of rock post-peak are mainly formed by the constant creep stage and the accelerated creep stage, the radial creep has a more obvious characteristic than the axial creep feature.The amount of the axial and radial strain is positively correlated with the damage degree, and the radial creep is more sensitive to the damage degree than axial creep.With Exerting the confining pressure increment,the axial and radial creep rate is greatly reduced and the creep instability time is prolonged.The effect of confining pressure increment on radial creep is stronger than that of axial creep,and the radial deformation of surrounding rock should be focused on controlling in engineering practice.
