Abstract
It is important to evaluate the factor affecting the tensile forces creating in geosynthetics comprising the liner of waste landfill such as waste weight and working vehicle for designing anchor trench at side slope crest. In this research, FEM analysis was performed for the field test with 5m height waste landfill model for evaluating the tensile forces creating in geosynthetics of liner. In the FEM analysis, the stress-strain relationship of geotextile and geomembrane are modeled by linear elastic and the stress-strain relationship of ash and friction stress-relative displacement relationship of joint element are modeled by hyperbola. By the calculations, the effects of geomembrane stiffness, load and placement of working vehicle on the tensile force were evaluated. The tensile forces of geosynthetics for the liner with two layers of geomembrane are also estimated comparing with the liner with one layer.
