Abstract

The invention discloses a multifunctional ring shear instrument. The multifunctional ring shear instrument includes a driving module, a sample shearing box set and a vertical pressure device, whereinthe driving module includes a load gear and multiple driving device sets matched with the load gear, rotational speeds of the load gear driven by the multiple driving device sets have different rotational speed ranges, the respective rotational speed ranges of the multiple driving device sets are continuously transitioned, the sample shearing box set includes multiple sample shearing boxes, the multiple sample shearing boxes can be alternately arranged at the driving module to adapt to multiple types of shearing experiments, and the vertical pressure device is arranged at the bottom to apply the vertical pressure to an experiment sample. The multifunctional ring shear instrument is advantaged in that shearing strength of cyclic test samples of various sizes can be measured, the shearing speed range is large, and shearing test requirements under various speed conditions can be satisfied.

Description

technical field [0001] The invention relates to the technical field of a ring shear instrument, in particular to a multifunctional ring shear instrument. Background technique [0002] In the discipline of civil engineering, the research on the residual strength of soil has always been the focus of attention at home and abroad, and the ring shear instrument can realize the functions of controllable and continuous shear displacement and constant shear area, so it can be considered that the ring shear instrument can be used in soil rock It plays an important role in the research of class residual strength. A general conventional ring shearing instrument uses a direct connection between a motor and a reducer or a gear box to drive the lower shearing box to rotate, and the upper shearing box is fixed in a different way. The velocity relative to the rotation shears the test specimen inside. [0003] The shearing speed of the current ring shear instrument can only meet the speed ...
