Abstract
A true triaxial testing system for disturbance experiment with broadband and low amplitude of a high pressure hard rock includes a low-frequency disturbance true triaxial mechanism, a variable-frequency low-speed disturbance rod mechanism and a rapid single-side unloading type specimen box. The low-frequency disturbance true triaxial mechanism and the variable-frequency low-speed disturbance rod mechanism are distributed along a straight line. The low-frequency disturbance true triaxial mechanism is independently used or cooperates with the variable-frequency low-speed disturbance rod mechanism for use. The rapid single-side unloading type specimen box cooperates with the low-frequency disturbance true triaxial mechanism for use.
