A Large-Scale Ramp Model Test on Composite Liner Systems
Abstract Composite liner systems comprising geosynthetics are widely used in landfills. In this paper, a large- scale ramp model test was carried out to simulate the sliding along the interface of GT/GM liner. The simulation test was performed by using a purposely-design set-up in the Zhejiang University large model box for foundation and slope engineering. The composite liner laid on a sloping foundation was loaded to a vertical stress level of 75 kPa, and a sliding along the GT/GM interface was successfully simulated by removing the lateral support. The softening behavior of the GT/GM interface during the sliding process was revealed. The experimental results of GT/GM liner system show that when the shear stress induced by the vertical loading exceeds the peak shear strength of the GT/GM interface, the GT/GM interface quickly fell into a residual shearing condition, and the tension stress in GT would increase sharply.
