Abstract

The application discloses a shear test device. The shear device comprises a test container and a rotary shear loading device; the test container is used for holding a to-be-tested sample and at least comprises a bottom plate and a side wall; the bottom plate of the test container is provided with an axial hole for placing a shear plate rotating shaft; the rotary shear loading device comprises a shear plate and a torque applying device, wherein the shear plate is installed on the axial hole of the bottom plate of the test container through the shear plate rotating shaft and can rotate around the shear plate rotating shaft; the torque applying device is used for driving the shear plate to rotate around the shear plate rotating shaft and realizing the rotating shear of the to-be-tested sample held in the test container. The shear test device and method have the advantages of realizing fixed area of a shear face, uniform stress of the shear face, and unlimited shearing displacement during the shear test process, and meeting the testing requirement of wide particle size of the test sample.

Description

technical field [0001] The present application relates to the technical field of testing soil mechanical properties, in particular to a shear test device, and also to a method for performing a shear test using the shear test device. Background technique [0002] The shear strength of soil refers to the ultimate ability of soil to resist shear failure. After the soil is subjected to load, it will produce normal stress and shear stress. Among them, the normal stress makes the soil compact, and the shear stress acts The soil can be sheared. Therefore, the strength of the soil often refers to the shear strength, and the strength failure of the soil is usually shear failure. For various artificially filled geotechnical structures, natural foundations, slopes, etc., the shear strength is an important indicator for safety evaluation. [0003] Under the prior art, soil shear test devices mainly include direct shear apparatus, ring shear apparatus, and cross-plate shear apparatus, e...
