Abstract
Basing on Frictional State Theory, the natural state parameter for sand is defined as an extension of state parameter proposed by Been and Jefferies. It is shown that for sand sheared at drained triaxial compression at failure and post-failure, sand behaviour is purely frictional and natural state parameter is ψ° ≈ 0. This parameter can be used for prediction of sand strength and modeling in the future.
