Name Institution Date Lab Report: Triaxial Abstract This experiment aimed at determining the undrained shear strength of soil using triaxial compression test. This was done by extruding a sample from a tube and trimming it to the size required. The sample was sleeved with a rubber membrane.
The clisp studio was then set up followed by completing the Pressurising Triaxial Cell checklist. The test stages were then made to run. After completing the stages, the test was terminated using the Clip Studio. The next procedure was completing the Draining Triaxial Cell checklist. The end point was the mohr cicle, for each of the sampled, the angle of shearing resistance of the soil and the apparent cohesion Introduction The triaxial shear test is a method that is commonly used in measuring the mechanical properties of deformable solids such as rock, granular materials, powder, and soil (Byrne 34). For loose granular material such as gravel or sand, the material is often contained in cylindrical latex sleeve with platen closing off the bottom and top ends (Byrne 25). Such as cylinder is immersed in a water bath or any other fluid, which provides pressure along the cylinder sides. Then the top platen is mechanically driven along the cylinder axis with a view to squeeze the material. Generally, there are a number of variations on the test. Although the term triaxial tends to suggest that stresses may be different in 3 directions, this may not be true. In this test with water or oil as a confining medium, confining pressures are all equal in all the directions. ...
