The NT-ZJ Quadruple Strain-Controlled Direct Shear Tester is a specialized device used to measure the shear strength of soil samples under controlled conditions. This instrument allows for the simultaneous testing of four soil specimens, each subjected to different vertical pressures. A shear force is then applied until the sample fails, and the corresponding shear stress at failure is recorded. The results are analyzed using Coulomb's Law to determine key geotechnical parameters such as the internal friction angle and cohesion.
Key technical specifications of the NT-ZJ model include:
1. Maximum vertical load: 400 kPa
2. Pressure levels: 100, 200, 300, and 400 kPa
3. Load ratio: 1:12
4. Shear box dimensions: 4 units
5. Maximum horizontal shear force: 1.2 kN
6. Specimen area: 30 cm² × 2 cm (height)
7. Shear rate options: 2.4, 0.8, 0.1, and 0.02 mm/min
8. Power consumption: Less than 100 W
9. Voltage requirement: 220 V ± 10%, 50 Hz
10. Instrument dimensions: 680 × 740 × 1050 mm (L × W × H)
11. Weight: 200 kg
This direct shear apparatus is widely used in geotechnical laboratories for evaluating the mechanical properties of soils, providing essential data for foundation design, slope stability analysis, and earthworks planning. Its strain-controlled mechanism ensures precise and consistent results, making it an invaluable tool for engineers and researchers in the field of soil mechanics.
