Direct Shear Test Apparatus, Color : Blue, Brand Name : V-TECH

Description
The Direct Shear Test Apparatus  is a soil testing instrument used to determine the shear strength parameters of soil, including cohesion (c) and angle of internal friction (ϕ). The apparatus applies a horizontal shear force to a soil specimen under a constant vertical load to measure shear resistance at failure. It is widely used in geotechnical engineering, foundation design, slope stability analysis, retaining wall design, and earthworks.

Key Features

• Determines shear strength parameters (c and ϕ) under controlled normal stress.

• Rigid and stable frame ensures accurate load transmission.

• Interchangeable shear boxes for different soil types and specimen sizes.

• Available as manual or motorized movement apparatus.

• High precision dial gauges / digital measurement options for improved accuracy.

• Comes with water tank for saturated soil testing conditions.

• Suitable for both laboratory and educational use.

Applications

1. Foundation Design
   Helps determine soil bearing capacity and stability under load.

2. Slope Stability Analysis
   Used to assess soil resistance against slope or embankment failure.

3. Retaining Wall and Earth Pressure Studies
   Provides shear parameters required for structural earth retaining systems.

4. Pavement and Road Subgrade Evaluation
   Used in selecting suitable soil types and compaction parameters.

5. Geotechnical Research and Quality Control
   Common tool in soil testing laboratories and civil engineering institutes.
