Abstract

The soft plastic mixed into solid waste landfills exhibits a reinforcing effect similar to that of geotextiles and significantly affects the assessment of slope stability. However, little research has focused on the reinforcing effect of soft plastic. In this study, the tension force generated on soft plastic under effective stress changes caused by gas pressure or pore water pressure was measured using strain gauges. The tension force corresponded with Terzaghi's principle with respect to the increasing or decreasing tendency; however, the relationship between the tension force and effective stress decreased parabolically with decreasing effective stress. In particular, tension force decreased rapidly after the effective stress decreased by half.
