![]() Standard:Ī) Shear box, 60 mm square & 50 mm deep so that sample of size 60 x 60 x 20 mm may be tested. You must understand the nature of shearing resistance in order to analyze the soil stability problems such as īearing capacity, slope stability and lateral pressure on the earth retaining structures. To familiarize the young Engineers with a procedure for rapidly estimating the shear strength Parameters (angle of friction and cohesion) of a soil sample. This information is necessary for substructure analyses, in determining the bearing capacity of the soil, in stability calculations of earth slopes, in pile driving, and other earthworks. The purpose of the direct shear test of soil is to obtain its ultimate shear resistance, its angle of internal friction, its cohesion, and its shear stress deformation characteristics. ![]() Read Also: Proctor Test Its Apparatus, Procedure, Result.
