Analysis of a Large-Scale Physical Model of Geosynthetic-Reinforced Piled Embankment and Analytical Design Methods

The piled embankment represents one of the solutions for realization a soil body on compressible subsoil where extended settlement or insufficient stability threatens serviceability related structures. Widely adopted analytical design procedures were analyzed: Marston’s formula and Hewlett Randolph method contained in British standard BS 8006-1, German regulation EBGEO Dutch CUR 226. Using these recommendations, theoretical values individual parts load acting and, subsequently, axial strain tensile forces reinforcement determined compared with experimental data obtained from tests large-scale physical model. For presented case, without support, 226 inverse load, which is recommended case low bearing capacity, shows better coincidence measured data. Overall, can be considered to close real behavior embankment. Because frequent utilization geosynthetic possible changes parameters during service life embankment, rheological process its elements should investigated process.
