This international standard specifies a method for consolidated triaxial compression tests on water-saturated soils.
This international standard is applicable to the laboratory determination of triaxial shear strength under compression loading within the scope of geotechnical investigations.
The cylindrical specimen, which may comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic or an anisotropic stress under drained conditions and thereafter is sheared under undrained or drained conditions. The test allows the determination of shear strength, stress-strain relationships and effective stress paths. All stresses and strains are denoted as positive numerical values in compression.
Special procedures such as:
a) tests with lubricated ends;
b) multi-stage tests;
c) tests with zero lateral strain (K0) consolidation;
d) tests with local measurement of strain or local measurement of pore pressure;
e) tests without rubber membranes;
f) extension tests;
g) shearing where cell pressure varies;
h) shearing at constant volume
are not fully covered in this standard procedure. However, these specific tests may refer to general procedures described in this standard.
NOTE – This document fulfils the requirements of consolidated triaxial compression tests for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.
