Contaminant containment measures are often necessary to prevent or minimize offsite
movement of contaminated materials for disposal or other purposes when they can be …

Soil pollution is one of the major threats to the environment and jeopardizes the provision of
key soil ecosystem services. Vertical barriers, including slurry trench walls and walls …

The stress state of the SB backfill in a full-scale cutoff wall test during the construction and
consolidation was simulated by a finite-element model. The applicability of the model was …

The results of a laboratory investigation on the effects of drying and wetting on the hydro-
mechanical behaviour of a cement–bentonite mixture are presented. A large hysteresis …

Cutoff wall has been widely used as a barrier to prevent the migration of contaminants in
aquifers. Hydraulic impermeability and homogeneity should be ensured before operation …

Soil-bentonite (SB) cutoff walls are commonly employed to control groundwater flow and
contaminant migration, and the hydraulic conductivity (k) of the SB backfill is a critical …

Low permeability barrier has emerged as a promising, cost-effective technology for anti-
seepage and pollution mitigation in geotechnical engineering. However, its efficacy in …

A long-term in situ test was performed on two soil–bentonite (SB) cutoff walls with different
dimensions. The total stresses and pore pressures in the walls were monitored for 8 months …

The trench cutting re-mixing deep wall (TRD) is a new type of underground waterproof
curtain. Mixing uniformity is the key index affecting the efficiency and quality of this method …

In this work, we describe our approach and experiences bringing an instrumented soil-
bentonite slurry trench cutoff wall into a modern IoT data collection and visualization …
