Abstract
A shear box of shear rheology experiment of a soft rock for simulating the coupling of the rainfall seepage and blasting vibration includes an upper shear box, a lower shear box, a normally-loading indenter, a normally-loading cushion block and a test piece joint. The upper shear box is tightly connected to the lower shear box by a vertical roll. The vertical roll passes through the through holes at both sides of the upper shear box and is engaged with the lower shear box through female thread connection holes. The normally-loading indenter passes through a circular through hole and presses against the normally-loading cushion block. The first end of the test piece joint is installed into a water or gas outlet hole, and the second end of the test piece joint is directly mortised into a rock test piece.
