A MODEL WITH TWO YIELD SURFACES FOR SOILS ---PROCEEDINGS OF THE PREDICTION SYMPOSIUM ON A REINFORCED EMBANKMENT ON SOFT GROUND, 17-18 SEPTEMBER 1986, KING'S COLLEGE, DEPT OF CIVIL ENGINEERING, LONDON

This article describes a new stress-strain relationship model for analysing the mechanisms of soil deformation. The model has two yield surfaces: one is elliptic, which relates to the compression. The other is parabolic, which relates to dilation. Comparison of calculated results using the model with the measured ones shows that the model can fit a wide range of soils and loading conditions, and can reflect shear dilation. There are only 8 parameters in the model, easy to be determined. It is a model convenient to be used. For the covering abstract of the conference see IRRD 819605.
