The use of one-dimensional compression tests and elastic theory in predicting deformations of rockfill embankments

Abstract

A laboratory investigation into the deformation behaviour of a rockfill material undergoing anisotropic compression at different stress ratios is described. The extent to which elastic parameters derived from one-dimensional compression can predict the behaviour of the rockfill at other stress ratios is considered. Stress paths encountered in embankments of cohesionless fill are examined and the relevance of elastic parameters derived from one-dimensional compression tests in analysing the deformations of such embankments is assessed.
