Swelling deformation of buffer material has been measured using buffer material swelling sensor on the full-scale in-situ engineered barrier system experiment. The sensor consists of strain gauges and is installed between the buffer material and backfill. This study reports the calculation result of the swelling deformation from measured strain values.
