Abstract
A true triaxial time-dependent dynamic disturbance test device for a deep-buried hard rock includes a rigid static load loading assembly and a rigid dynamic load loading assembly. The rigid static load loading assembly applies a static load to a rock test sample, and the rigid dynamic load loading assembly applies a disturbance stress to the rock test sample. Coupled application and control of a long time-dependent static force and a disturbance stress of the rock in a true triaxial disturbance stress state are achieved. The rigid dynamic load is provided with a disturbance rod in a loading direction, and a 'point' disturbance mode is converted into a “face” disturbance mode through the disturbance rod, a disturbance hole and a test sample clamp, so that a disturbance mode more suitable for an actual working condition on site is provided while power consumption is reduced and time-dependent dynamic disturbance is achieved.
