Integrated style shear apparatus for rock structural plane and a shear experimental method for rock structural plane

Abstract

An integrated style shear apparatus for rock structural plane comprises a frame system, a vertical loading system, a horizontal loading system, and a shearing system. Both the vertical loading system and the horizontal loading system are fixed on, and the shearing system is installed inside the frame system. The shearing system is used to prepare the sample of structural plane and actualize the shear test, the vertical loading system and the horizontal loading system are used to provide normal stress and shear stress for the shearing system respectively. The present invention also provides an experimental method by using the integrated style shear apparatus for rock structural plane, and steps of the method including: sample placement, sample adjustment, sample preparation, sample loading, instrument hookup, exerting normal stress, exerting horizontal stress, measurement and description of shear area, repeating experiment, and normal stress and shear stress calculation. The present invention can effectively reduce sample preparation error and experimental error, and can rapidly and accurately determine shear strength and deformation parameters of rock structural plane.
