AASHTO T 226 90th Edition, January 1, 1990 Standard Method of Test for Triaxial Compressive Strength of Undrained Rock Core Specimens without Pore Pressure Measurements
More info
Description / Abstract:
This test method covers the determination of the strength of
cylindrical rock specimens in an undrained state under triaxial
compression loading. The test provides data useful in determining
the strength and elastic properties of rock, namely: shear
strengths at various lateral pressures, angle of internal friction
(angle of shearing resistance), cohesion intercept, and Young's
modulus. It should be observed that this method makes no provision
for pore pressure measurements. Thus the strength values determined
are in terms of total stress that is not corrected for pore
pressures.
