摘要：Soft rock-like specimens with different single-fracture angles were prepared by using similar materials. Uniaxial and triaxial creep tests and confining pressure unloading tests were carried out for single-fracture rock-like specimens with different angles. The results show that the steady-state creep rate shows a parabolic trend with the change of angle under the same load. The steady-state creep rate increases first with the increase of angle, then decreases with the increase of angle. The steady-state creep rate peaks at about 30 degrees, and the steady-state creep rate of the complete specimen is the smallest.
