Summary This paper deals with a model for time‐dependent compaction of soil‐like porous materials. Although the model is originally developed for degradation‐induced settlements in municipal solid waste landfills, it may be applied to any settlements caused by solid mass loss as well. The presented model is part of a coupled THMC model, that is, a model that considers coupled thermal, hydraulical, mechanical and chemical effects. The Theory of Porous Media is used as continuum mechanical framework. For kinematic description, large strain continuum mechanics are applied. The paper provides a brief insight into the coupled model, but concentrates on the description of the compaction model and its application within coupled analyses of a laboratory experiment and a landfill structure.
