ZJ Light-Duty Strain Controlled Direct Shear Apparatus
Application:
ZJ Light-duty Strain Controlled Direct Shear Apparatus is a kind of strain controlled direct shear apparatus used to test resisting shear strength of soil specimen, it usually adopts four specimens under the different vertical pressure(50, 100, 200, 300, 400kPa (hanger is first grade)), to exert horizontal force to the specimens, so as to obtain shearing stress while the specimen is damaged. According to Coulomb’ s rule, it is to confirm the soil resisting shear strength coefficient, angle of internal friction and coagulable force
Standard:
GB/T 50123-2019 Standard for geotechnical testing method
SL237-1999 Specification of soil test
JTG E40-2007 Test methods of soils for highway engineering
