In a cell, the triaxial test is performed on a cylindrical soil sample with a length-to-diameter ratio of 2 to calculate the shear strength of the soil. The standard dimensions are 76 mm x 38 mm and 100 mm x 50 mm. Three principal stresses are applied to the soil sample.

WebThe shear strength of soil is usually determined experimentally by one of the following methods. 1. Direct Shear Test. 2. Laterally Confined compression test, also known as the triaxial compression test. 3. Unconfined … WebIntroduction. Triaxial tests are widely used in geotechnical engineering both in soil and rock mechanics. Specimens are axially loaded to failure while a confining pressure is constantly applied. As a result, the behavior of geomaterials is investigated in a three-dimensional stress state. The principal stresses (the maximum and minimum normal ...
A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders. There are several variations on the test.
