Abstract
<jats:p>Recent publication reported that void ratio is not a good state variable for sand with fines. Thus, equivalent granular void ratio, e*has been proposed to resolve this problem. The Steady State data points in the e*&minus;log&lpar;p&prime;&rpar; space can be described by a single trend irrespective of fines content, fc, provided fc&le;TFC. This single trend line is referred to equivalent granular steady state line, EG-SSL. However, whether the EG-SSL can be used within the context of critical state soil mechanics (CSSM) for predicting undrained behaviour has to be investigated. An equivalent granular state parameter, &psi;*, defined using EG-SSL as the reference is proposed in this paper. It is found that &psi;*can successfully predict undrained responses of sand with fines in undrained shearing.</jats:p>
