摘要：
In this paper, the deterministic parameter identification procedure proposed in a companion paper is applied to suction-dependent elasto-plasticity problems. A mathematical model for such type of problems is firstly presented, then it is applied to the parameter identification using laboratory data. The identification procedure is applied in a second example to exploitation of a gas reservoir. The effects of the extraction of underground fluids appear during and after quite long periods of time and strongly condition the decision to profit or not of the natural resources. Identification procedures can be very useful tools for reliable long-term predictions. Copyright (C) 2001 John Wiley & Sons, Ltd.
