How Geosynthetic Reinforcement Supports the Piled Embankment: A Numerical Approach
The modern approach to the piled embankment includes the basal reinforcement of geosynthetic layers. Current design guidelines for piled embankment in the Netherlands, Germany, and U.K. have been updated to accurately estimate the practical tensile strains of employed geosynthetics, whereas the analytical approaches were usually underestimated against the experiment and in-situ results. In this study, a series of finite element simulations concerning different types of soil-geosynthetics interaction were conducted to reveal the difference of frictional modeling method. The geosynthetic strains along the diagonal and orthogonal direction from the pile center toward to the other pile were obtained according to the loading condition. The completely different responses were observed with respect to the type of the frictional model.
