Zusammenfassung:Geosynthetic clay liners (GCLs) have been expected to be used as hydraulic barriers in the cover system, particularly for containment of hazardous wastes. A trapdoor test was performed to investigate the behavior of overlapped GCLs subjected to differential settlements, under a small overburden pressure simulating the use of GCL as a landfill cover barrier. In addition, soil tank tests were performed to measure the hydraulic barrier performance of overlapped GCLs section subjected to slippage of up to 100 mm and a decreased overburden pressure, due to the differential settlement. The testing results presented that an overlapped GCLs section subjected to differential settlements of up to 150 mm maintained its hydraulic integrity under the tested condition
