Method of Test for Strength Parameters of Soils by Triaxial Compression Tests

This method of testing enables the determination of the strength parameters of soils. The methods described are the consolidated undrained triaxial compression test--with or without pore pressure measurements--and the unconfined compressive strength test. The parameters obtained are the angle of internal friction, ∅, the cohesion, c, and the unconfined compressive strength. The values so obtained may be employed in the design and analysis of earth structures--with consideration of the accepted criteria of stability and safety
