(8) Set the vertical load (or pressure) to a predetermined value, and then close bleeder valve and apply the load to the soil specimen by raising the toggle switch. WebDead-Weight Direct Shear Machines by Karol-Warner are motorized units for direct and direct/residual shear testing of soil samples and use a 10:1 dead-weight beam loading system to apply vertical confining pressures. These compact, self-contained units have similar designs but differ in instrumentation for data measurement and collection.
WebA vertical confining load is applied to consolidate the soil, then a horizontal shear load is applied, laterally displacing one-half of the Shear Box at a constant rate while measuring the required force and amount of displacement. For residual shear tests, the displacement direction is reversed and the force measured.
