Abstract

The invention provides a circular angle and circular displacement measurement apparatus and method, which relates to the technical field of circular shear test. The circular angle and circular displacement measurement apparatus comprises a measurement sliding block, a measurement sensor and a support. The measurement sliding block is installed on a shearing box, the measurement sensor is connectedwith the measurement sliding block, and the measurement sensor are fixedly installed on the support. The shearing box is used for performing the circular shear test for a test sample, when in the circular shear test, the measurement sliding block rotates along the shearing box, the measurement sliding block rotates to enable the measurement sensor to produce axial displacement, so that a circularangle and circular displacement of the shearing box can be calculated by virtue of the measurement sensor, the measurement is convenient, and a test result is accurate. The circular angle and circular displacement measurement method provided by the invention is simple in operation, precise in measurement and capable of increasing the circular shear test efficiency and success rate.

Description

technical field [0001] The invention relates to the technical field of ring shear tests, in particular to a device and method for measuring ring angle and ring displacement. Background technique [0002] The shear strength of rock is one of the important indicators to evaluate the mechanical properties of rock, and the accurate acquisition of strength parameters has important practical significance for rock mass engineering. At present, the shear strength of rock is mainly obtained through laboratory tests. The main test types include: conventional triaxial test, direct shear test and wedge shear test. [0003] Analyzing the existing test implementation methods, the force on the shear surface of the rock is not uniform during the shearing process, and the deformation is delayed, which cannot accurately reflect the shear strength of the rock. The rock tension-compression ring shear tester adopts a ring sample and applies torsion to make the rock uniformly stressed and deform...
