A thermo-mechanical model for variably saturated soils based on hypoplasticity

Popis výsledku v původním jazyce

The paper presents a mechanical model for non-isothermal behaviour of unsaturated soils. The model is based on an incrementally non-linear hypoplastic model for saturated clays and can therefore tackle the non-linear behaviour of overconsolidated soils.A hypoplastic model for non-isothermal behaviour of saturated soils was developed and combined with the existing hypoplastic model for unsaturated soils based on the effective stress principle. Features of the soil behaviour that are included into the model, and those that are not, are clearly distinguished. The number of model parameters is kept to a minimum, and they all have a clear physical interpretation, to facilitate the model usefulness for practical applications. The step-by-step procedure usedfor the parameter calibration is described. The model is finally evaluated using a comprehensive set of experimental data for the thermo-mechanical behaviour of an unsaturated compacted silt. Copyright (c) 2011 John Wiley & Sons, Ltd.
