Abstract

A one-dimensional analytical model has been developed to describe the compressive behaviour of clay-based shaft backfills under large hydraulic loads. The analytical model has been calibrated with results from a compression test on a partially saturated swelling clay backfill mix in the high-pressure compression cell constructed at Ontario Hydro.
