Abstract

Needle-punched geosynthetic clay liner (NPGCL) has been widely used in landfills. The internal strength of the GCL changes with temperature variation, which affects its application in landfills. A large-scale temperature-controlled direct shear apparatus was developed to study the internal shear strength characteristics of GCL affected by temperature. The internal strength of the GCL was dependent on the bentonite, the fibers, and the interaction between the fibers and the bentonite. The influence of temperature on the internal strength of the GCL was mainly reflected in the displacement at peak strength. However, the peak strength was basically unchanged. The strength of the bentonite and the fibers-reinforced bentonite increased when the temperature increased. The tensile strength of needle-punched fibers decreased with increasing temperature. The peak strength displacement of the fibers-reinforced bentonite decreased with increasing temperature.
