Description:
The document reviews current design and construction methods of soil-bentonite slurry trench cutoff walls. It summarizes engineering practices, identifies areas of technical detail and initiates research to promote the development of standards for use of slurry walls to isolate hazardous waste. An instrumented slurry test column was developed and used to investigate the hydraulic characteristics of bentonite slurry seals formed, during construction, on cutoff trench walls. A slurry wall tank was used to evaluate the effects of overburden pressure and hydraulic gradient to evaluate the potential for self-remediation of hydraulic defects via in situ consolidation of soil-bentonite backfill.
