The Study on Strength Criterion for Sands Under 3D Condition

Abstract

In order to describe the strength characteristics of sands in true triaxial tests preferably, the dependent shape function of Mohr-Coulomb's strength criterion is modified based on true triaxial tests results. Then the true triaxial test results of Shanghai fine sands are simulated. The good predictions show that the strength criterion based upon true triaxial tests can describe the strength characteristics of sands in true 3D state more exactly.
