Abstract

The invention belongs to the field of a direct shear test and a direct shear rheological test of a complete rock block with a cylindrical core or a rock block with a structural surface under a complex occurrence condition of simulating deep ground engineering, and particularly relates to a direct shear rheological testing machine for a cylindrical surface of the cylindrical core in a deep ground environment. The machine structurally comprises a shearing pressure head and a horizontal driving mechanism, wherein the shearing pressure head is provided with a base, a sample clamping seat and an angle adjusting screw rod. According to the cylindrical core cylindrical surface direct shear rheological testing machine in the deep ground environment, a shear test can be directly carried out on the cylindrical complete rock block and the cylindrical rock block containing a structural surface, and the problem that the shear test cannot be effectively carried out due to restrictions of the size, the character and the like is solved.

Description

technical field

[0001] The invention belongs to the field of direct shear test and direct shear rheological test of a complete rock block of a cylindrical core or a rock block with a structural surface under the complex occurrence conditions of a simulated deep-earth engineering, in particular to the direct shear of a cylindrical core cylinder in a deep-earth environment Rheological testing machine. 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...
