Overview
The strain control method of the coarse-grained soil direct shear instrument is that the large direct shear instrument is vertically loaded with a hydraulic cylinder, which complies with GB/T50123-2019 "Soil Test Method Standard". It adopts the stress controlled push method and is suitable for the shear test of coarse-grained soil. The instrument consists of three parts: a four column loading host, a hydraulic pump station system, and a microcomputer control system. The loading host consists of a base, support column, crossbeam, vertical loading hydraulic cylinder, horizontal loading hydraulic cylinder, shear box, ball row, guide rail, etc.
