抄録

A large-scale field test was carried out to investigate the backfill consolidation behavior of soil-bentonite slurry trench cutoff walls. The results of lateral earth pressure, pore pressure and deformation monitoring show that the weight of SB backfill is initially taken by pore water and sidewall friction, and then is transferred to backfill skeleton due to consolidation. The findings from this large-scale test help understand the stress states of backfill and assess the performance of soil-bentonite slurry trench cutoff walls.
