Manual direct shear machine in Bangladesh

The concept of manual direct shear is simple and mostly recommended for granular soils, sometimes on soils containing some cohesive soil content.

The cohesive soils have issues regarding controlling the strain rates to drained or untrained loading. In granular soils, loading can always assumed to be drained. A schematic diagram of shear box shows that soil sample is placed in a square box which is split into upper and lower halves.

More details:

Lower section of direct shear machine is fixed and upper section is pushed or pulled horizontally relative to other section; thus forcing the soil sample to shear/fail along the horizontal plane separating two halves. Under a specific Normal force, the Shear force is increased from zero until the sample is fully sheared.

The relationship of Normal stress and Shear stress at failure gives the failure envelope of the soil and provide the shear strength parameters (cohesion and internal friction angle

Need and scope:

The value internal friction angle and cohesion of the soil are required for design of many engineering problems such as foundations, retaining walls, bridges, sheet piling. Direct shear test can predict these parameters quickly

Procedure:

  • Check the inner dimension of the soil container, and put the parts of the soil container together.
  •  Calculate the volume of the container. Weigh the container.
  • Place the soil in smooth layers (approximately 10 mm thick). If a dense sample is desired tamp the soil.
  • Weigh the soil container, and find the weight of soil. Calculate the density of soil.
  • Plane the top surface of soil, and put the upper grating stone and loading block on top of soil.
  • Measure the thickness of soil specimen
