Study of the design method of using geonets to treat the unequalsettlement of subgrade at the cut to fill location

Authors place reinforcement materials such as geonets layered in the filling soil in order to solve the problem of unequal settlement of subgrade at the cut to fill location.In this paper, by using nonlinear FEM, authors analyzed the mechanism of using geonets to treat this kind of unequal settlement based on tests on settlement and deflection by FWD in site. So,the design method using reinforcement materials to treat this kind of unequal settlement is put forward.
