The shear stress at failure is determined according to Coulomb’s law Shear strength coefficient, internal friction angle, and cohesion.
| Vertical load | 100KPa, 200KPa, 300KPa, 400KPa, 50KPa, can choose different loads |
|---|---|
| Horizontal load | 1.2KN |
| Leverage ratio | 1:20 |
| Specimen area | 30c㎡ |
The ZJ-1A strain-controlled value shear instrument is used to determine the shear strength of the soil. Usually, four specimens are used under different vertical pressures to apply shear force for shearing. The shear stress at failure is determined according to Coulomb’s law Shear strength coefficient, internal friction angle, and cohesion.
