Triaxial Shear Test

Introduction to Geotechnical Engineering

Learning objectives of the presentation:

  • Describe the boundary stress conditions for the unconfined compression test.
  • Sketch the setup for a triaxial test showing applied loads and stresses.
  • Draw a free body diagram of a soil specimen in a triaxial test.
  • Given triaxial test data, plot both the total and effective Mohr-circles and determine the strength parameters.
