Abstract : Laboratory tests, partially confirmed by field data, demonstrate that the swelling of freshwater clay exhibits small clay swell expansion (depending upon the initial water content) and additional ice expansion due to ice lense formation. Ice lense formation is enabled only if the freezing process is accompanies by simultaneous water uptake from the bottom. If the natural condition of a sample is almost water saturated, as was the case during sampling in the fall of 1983, the clay represents an already expanded condition.
