CONSTANT VOLUME SHEAR BEHAVIOR OF SANDY SOILS UNDER HIGH CONFINING PRESSURE

Abstract

In order to investigate the behavior of dense sandy soils under high confining pressure, high-pressure triaxial tests were performed on three types of undisturbed specimens. As a result, it is confirmed that consolidation and shear characteristics of undisturbed dense sandy soils are similar to those of clayey soils. Under high confining pressure, the yielding stress of consolidation exists influencing the shear characteristics at the point. Through grain-size analysis, it was found that particle crushing increased with consolidation stress and was remarkable when the stress exceeded the yielding stress.
