Abstract

The invention belongs to the field of axial shear test and shear rheological test of cylindrical rock or rock with structure plane under the complex occurrence conditions of simulated deep ground engineering, and particularly relates to a rock shear rheological test machine in deep ground environment. The specific structure These are: frame, test support platform, upper indenter and lower indenter. The rock shear rheological testing machine in the deep environment realizes the shear test directly on the columnar core and the columnar core with structural surface, which solves the problem that the shear test cannot be effectively carried out due to the constraints of size and shape.

Description

technical field [0001] The invention belongs to the field of axial shear test and shear rheological test of cylindrical rock or rock with structural plane under the complex occurrence conditions of simulated deep ground engineering, in particular to a rock shear rheological test machine for deep ground engineering. Background technique [0002] The shear mechanical property of rock is one of the essential key mechanical parameters in rock mass engineering construction. For deep engineering rock mass buried underground, its occurrence environment is usually the joint effect of high stress and high osmotic pressure, and even faces the coupling effect of high temperature. Under high stress and high osmotic pressure, the shear strength and Deformation characteristics are particularly important to engineering safety, especially for engineering rock masses with significant rheological properties, and their rheological properties under shear loads are also the first thing to be mas...
