Determine friction angle from triaxial test
The triaxial shear test is the most versatile of all of the methods for testing the shear strength of soil and finding its cohesion (c) and angle of internal friction (φ). It can measure the total, as well as the effective stress parameters, and can be conducted on any type of soil. Drainage conditions can be controlled, and pore … See more ASTM D4767: Standard Test Method for Consolidated Undrained Triaxial Compression Test for Cohesive Soils See more http://www.ce.memphis.edu/7132/Slides%20for%20Students/13%20-%20Stress%20Paths%20and%20Strength%20Tests.pdf

WebThe undrained triaxial strength tests are used to determine the shear strength of a soil sample that is not allowed to drain. The test will be completed on three unsaturated soil samples. The test results will be analyzed to determine the Mohr-Coulomb failure envelope, failure angle, shearing resistance, and Young’s Modulus of Elasticity.
