DIN EN ISO 17892-9:2016-11

This document specifies a method for consolidated triaxial compression tests on water- saturated soils. This document 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.
