Abstract：Characteristics of microstructure of till are studied. Behavior of stress-strain-volumetric change of till under high and low stresses is analysed systematically, and major factors affecting the behavior are also indicated. A new non-linear K-G model which involves volume dilatancy and stress working soften is proposed.
