On the basis of existing evidence a ease in made for achieving similarity between the laboratory test model

and the field prototype. The extent to which this similarity is both possible and necessary is explored in a series of tests

on a normally consolidated coarse sand. The tests are carried out using an automatic programmable triaxial test system

where a desktop computer is used to log and process test data and to control the test to allow the simultaneous appli-

cation of varying axial and radial stresses to simulate a field loading construction stress path. The insitu soil is modelled

by carrying out K0 consolidation in the conventional triztxial cell. The effects of undrained total stress relief sampling di-

sturbance is examined together with the effects of isotropic and anisotropic reconsolidation and the application of an idea-

lised construction stress path measured at the site of an embankment dam.
