Effect evaluation for the geocomposite reinforced embankment of cohesive soil

In recently years, the low quality soft clay from construction site increases rapidly, due to the development of urban and underground space. Combining the geosynthetics reinforcement with this surplus soil is one of the effective recycling methods. Considering a steep slope banking with high water content and low quality soil, the reinforcement effect of geocomposite is evaluated by using the finite difference analysis. In this study, it is clarified that the reinforcement mechanics of geocomposite for the improvement on the tension and drainage capability of embankment, and also some suggestions for the design of geocomposite reinforced embankment are proposed.
