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.

Point load test

“Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting”. Text from Using the point load test to determine the unxial compressive strength of coal measure rock. Stella Jhang Kerry Magner
