Abstract
A tester assembled by multiple sets of mechanisms for shear strength-scale effect of a rock joint includes a horizontal loading mechanism, a horizontal supporting and force-measuring mechanism and a sample installation and lifting table are mounted on a platform on the bottom of a frame, the horizontal loading mechanism and the horizontal supporting and force-measuring mechanism are respectively located on two sides of the sample installation and lifting table; rock joint sample is divided into an upper portion and a lower portion by a slit, the horizontal loading mechanism is configured to load the upper portion of the multi-scale rock joint sample, and the horizontal supporting and force-measuring mechanism is configured to support the lower portion of the multi-scale rock joint sample; a vertical loading mechanism is located above the multi-scale rock joint sample, and can be mounted on the frame in a manner of being movable up and down; and the horizontal loading mechanism comprises at least two tangential actuators, and the vertical loading mechanism comprises a vertical actuator group including at least two vertical actuators. The present invention effectively meets the test requirements on the scale of the multi-scale rock joint samples under large-range loads, and is good in reliability.
