Geoenvironmental study on solid waste landfill liner
MetadataShow full item record
Hydraulic performance, physical deformation and GCL response to permeants were investigated using powdered and granular GCLs, bentonite and sand. Pollute v.7 simulated contaminant-transport through liner-system, showing ~70% decline in lead and chromium after permeating semi-permeable layer. Sludge improved bentonite subgrade shear stability. Carbon reduced sand subgrade’s shear strength, while slag and wood increased. Slag also increased sand layer’s liquefaction-resistance. Plaxis2D FEM model showed wavy ground-surface deformation in sand aquifer by groundwater extraction and dynamic/seismic loading.
