The Shear box test on soils Institution Name Date Table of Contents References 5 The Shear box test on soils Introduction The Shear box test or commonly referred to as Direct Shear test is a field test or sometimes laboratory test employed by geotechnical engineers…
The shear box test has an advantage over test because of the simplicity of equipment used and the ease in setting it up. The Shear test box also tests soil samples under different conditions such as consolidation, drainage, and saturation conditions. Another advantage of the shear box test is that it is easy to visualize what is happening to the soil as the test is being carried out. Various processes using the shear box test determine these properties. In determining the soil, these properties the results of the test are tabulated and graphs are drawn. Interpretation of the graphs is what gives significant meaning to some of the soil properties being studied. Purpose of the test A shear box test is used in geotechnical engineering to test various properties of soil. These soil properties include; friction angle, peak shear strength, soil cohesion, and the residual shear strength of the soil being studied. The key purpose for carrying out the test is to enable geotechnical engineers decide on the consolidated-drained shear strength of a silt to sandy soil. Shear strength is a very important aspect in engineering when determining soil properties. This is because most structures are based on soil’s shearing strength or resistance. Therefore, any time a structure is to be constructed it is important that the soil’s shear resistance be analyzed as the first step to decide on the whether it will be possible to construct. ...
