PLASTIC POTENTIAL AND EFFECTIVE STRESS PATH IN ONE DIMENSIONAL CONSOLIDATION

Abstract

 The coefficient of earth pressure at rest is obviously important in geotechnical problems. The influence of a new plastic potential on the minor principal effective stress during one-dimensional consolidation is examined by finite element analysis. Results of experimental and numerical investigation indicate that the coefficient of earth pressure at rest K₀ during one-dimensional consolidation appears to be governed by the plastic potential and secondary compression time effects.
