Abstract
A numerical analysis is conducted on the performance of geogrid-reinforced cushion in PCC pile-supported composite foundation for highway embankment applications. The finite element method is employed to simulate the behavior of cushion under loads. Soil arching effect and tensile membrane effect are two factors affecting cushion behavior. Two parameters, i.e. geogrid tensile strength and laying arrangement, are found effective in measuring soil arching and tensile membrane effects. Numerical analyses indicate that an increased geogrid tensile strength contributes to a reduced embankment settlement. The effect of geogrid laying arrangement on settlement is relatively small.
