Abstract
The disclosure relates to a soft rock shear rheological test system with simulation of coupled rainfall seepage and blasting vibrations, which is at least provided with a loading device and a shear box. The loading device includes a frame (2), a normal static load electric cylinder (1) disposed on a top of the frame (2) and a normal dynamic load electric cylinder (16) disposed on a lower portion of the frame (2), a horizontal static load electric cylinder (5) and a horizontal dynamic load electric cylinder (12) disposed on both sides of the frame (2), and a reaction post (10). This test system can perform a dry-wet cycle operation on the test specimen without disassembling the shear box during the shear rheological test, and can truly simulate influences of rainfall seepage and blasting vibrations on the shear rheological effect of soft rock.
