PLANE STRAIN BEHAVIOUR OF GRANULAR MEDIUM

The paper briefly describes an equipment to test soil specimen under general stress systems including plane strain condition using flexible vertical faces. Results of tests conducted on a uniform sand in fully drained condition and on specimens isotropically and anisotropically consolidated and sheared in axisymmetric and plane strain condition, are described, compared and discussed. Expressions have been presented to predict plane strain strength from axisymmetric triaxial tests at any desired relative density. The predicted plane strain strength agrees well with experimental results of several investigators. It is found that secant modulus at failure strain is always higher in plane strain than in axisymmetric case. Anisotropy of consolidation stresses does not have much effect on secant modulus at failure strain. The axisymmetric triaxial specimens fail at higher volumetric strain but have lower volumetric strain rate compared to the plane strain specimen. The ratio octahedral shear strain at failure in axisymmetric to plane strain compression has been found to be nearly constant. An expression has been presented to predict strain ratio at failure from the plane strain compression strength. Anisotropy of consolidation stress has no effect on this ratio. (TRRL)
