Abstract
When waste is disposed or some vehicle moves on a liner of landfill, tension stress creates in geomembrane used as a liner. For estimeting the stress, it is important to consider the interface friction characteristic. As seen in the results of direct shear test, frictional resistance depends on the relative displacement of the interface. In this paper, the slip interface model where a relation between frictional resistance and relative displacement is approximated as hyperbolae is introduced to the two dimentional finite element method. Then calculation are conducted to simulate a centrifugal model tests.
