Triaxial compression testing is commonly used to simulate the stress conditions of rock as a function of confining pressure. This test method determines the strength of cylindrical rock specimens in an undrained state. It provides data in the strength and elastic properties of the rock.

 

Data entry and calculations for this test are performed on the Triaxial CompressiveStrength form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the reporting section below. The format of this report is controlled by the geotechnical template used for the test.

 

The methodology and calculations for this test adhere to "ASTM D2664-95s Standard Test Method for Triaxial Compressive Strength of Undrained Rock Core Specimens without Pore Pressure Measurements" and "ASTM D3148-96 Standard Test Method for Elastic Moduli of Intact Rock Core Specimens in Uniaxial Compression". For more detailed information on the methodology and calculations please review these standards.
