Drained shear behaviour of sand with inherent transverse isotropy, for various b values

K. Suzuki and E. Yanagisawa

Abstract

The objective of this paper is to reveal the fundamental characteristics of inherently anisotropic Toyoura sand for constant b values under drained conditions. To this end, monotonic loading tests with fixed principal stress axes and loading tests with rotation of the principal stress axes, were carried out using a large hollow cylindrical apparatus. Through analysis of the experimental results, characteristics related to the hardening law, the principal deviatoric strain increment ratio and the direction of the maximum principal strain increment etc. have been clarified, taking the effect of the b value into consideration.
