Impact of Geomembrane Defect on Leakage Rate of Landfill Composite Liner Under Mechanical–Chemical Coupled Conditions
Original research · free full-paper access · authors credited
Research overview
Hydraulic tests and finite-element modelling assess GCL–geomembrane composite liners with 2–7 mm circular defects under two effective stresses and calcium-chloride solutions. Smaller defects, lower solution concentration and higher stress reduced leakage, but the tested defective composite did not match the modelled leakage of a standard compacted-clay liner; specimen scale, selected GCL and idealised circular defects limit field transfer.
