The Influence of End Restraint and Method of Consolidation on the Drained Triaxial Compressive Strength of Crushed Napa Basalt,

Abstract

Tests were carried out on crushed Napa basalt in triaxial compression apparatus to examine the influence of boundary restraint and the method of consolidation (i.e., isotropic or Ko consolidation) on the observed stress-strain, volume change, strength, and crushing of the grains. To accomplish this objective, new enlarged low-friction end platens for the triaxial compression apparatus and a special specimen former were designed and constructed. The Ko consolidation phase of the test was conducted by using a special lateral strain sensor instrumented with strain gages and placed around the specimen. The lateral strain sensor is sensitive enough to detect any tendency for radial deformation during consolidation.
