Abstract

The purpose of municipal solid waste landfills (MSWLF) is to dispose non-recyclable materials, gas extraction, composting, and controlling of pollutants that threaten human health and the environment, and finally providing useful areas after filling. Since Iran is located on the seismic belt and has experienced some high intense earthquake, the study of the Tehran’s MSWLF landfill known as the Kahrizak landfill is important. Seismic loads may damage MSWLF through the relative movements within the waste, bottom lining system, cover system, foundation, and interfaces. The smooth synthetic materials might be placed beneath the structures to provide seismic protection by absorbing the imparted energy of earthquakes through the sliding mechanism. In the present study, experimental investigations were conducted in order to evaluate role of in-soil base isolation on seismic response of the Kahrizak MSW landfill. Shaking table tests were conducted on the MSW embankment isolated by semi-elliptic shaped liners and subjected to harmonic sinusoidal base excitations. Furthermore, the behavior of the physical shaking table model was investigated by numerical modeling. The results of the isolated and non-isolated cases are compared in terms of permanent displacement and seismic response. In this study, a good agreement was found between the results of the physical model and the large scale numerical model. Studies have shown that the use of a composite liner system with a further reduction in the friction coefficient results in a significant reduction in the amount of acceleration and displacement, and can protect the structure in seismic conditions. This method did not show a significant effect on the landfill settlement. The efficiency of this technique increases with increasing the amplitude of input motion employed in the current study. It was also observed that employing flat liner leads the movement of the ridge to the sides; and the concave liner prevents the wedge to move excessively.
