Abstract
In this study, proposed FEM analyses of pull-out tests ware conducted. This method was combined with joint element method. Frictional coefficient between water proof sheet and non-woven geotextile was identified by experimental analyses that water proof sheet was pulled out. Frictional coefficient between non-woven geotextile and soil was identified by the analyses of the test that non-woven geotextile was pulled out. Conclusively, FEM analyses of the tests that both water proof sheet and non-woven geotextile were pulled out were conducted by using identified frictional coefficients mentioned above. The calculated strains of water proof sheet and non-woven geotextile were compared with those of measured by tests. At the result, it was proved that we could evaluate quantitatively strains of water proof sheet and non-woven geotextile by proposed FEM analyses.
