A STATE PARAMETER FOR SANDS

The requirement for a rational engineering approach to constructing structures using undensified hydraulic sand fill has identified several deficiencies in current technology. In particular, there is no single parameter measure of sand behaviour. This paper presents an appropriate physical parameter, termed the state parameter, that combines the influence of void ratio and stress level with reference to an ultimate (steady) state to describe sand behaviour. Data from a triaxial testing programme on kogyuk sand with four fines contents is presented and the significant engineering design parameters are demonstrated to be dependent on the state parameter. The concept of state is a fundamental physical concept and has wide applicability both as an empirical normalizing parameter and for constitutive modelling soil behaviour. (Author/TRRL)
