Abstract

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