1. Direct Shear Test
1.1 Introduction
The Direct Shear Test is an investigation used by geotechnical engineers used to measure the shear strength properties of a soil. It is noted that the shear strength of a material is a term used to describe a materials ability to resist failing in the direction parallel to the applied force, and therefore an important soil property to be noted by engineers. In this lab test ‘Sydney Sand’ is used to determine the relationship between a given load and a change in cross-sectional area and also show the friction angle of the soil specimen, by testing the sample using what is commonly known as a shear box.
1.2 Test Procedure
Determination of Shear Strength of a Soil – AS 1289.6.2.2 (1998)
Points to consider within the test procedure include: The porous stones placed on the bottom and top of the soil sample not only act as a filler but help propagate a dense soil sample The soil sample was compacted in three layers as it was placed into the shear box
1.3 Results and Discussion
Given a drained soil sample of Sydney Sand of mass 139grams, at a constant density of 1930kg/m3, and the data plotted in Appendix A, the following graph has been obtained - relationship between shear force and horizontal displacement.
The dotted plots of the 5kg, 10kg,
