INSTRUMENTATION OF DREDGE SPOIL FOR LANDFILL CONSTRUCTION

The Delaware Solid Waste Authority's Northern Solid Waste Management Center is located near Wilmington at Cherry Island, a former dredge disposal site. Dredge spoils, of very low permeability, range in depths up to 30m (100ft) which form a natural "liner" and the foundation for the 140 ha (350-acre) solid waste landfill. The soils beneath the landfill have been extensively instrumented to measure pore pressure, settlement, and deflections, using inclinometer casings, standpipe piezometers, vibrating wire piezometers, pneumatic piezometers, settlement plates, liquid settlement gauges, total pressure cells, and thermistors. The nature of the existing waste and anticipated settlements have required some unique installation details. The instrumentation data has been integral in planning the landfilling sequence to maintain perimeter slope stability and has provided key geotechnical parameters needed for operation and construction of the landfill. This paper discusses the performance of the instrumentation and the monitoring results.
