The finite element analysis greatly enhances the understanding of the observations while the measurements give the finite element analysis substance. A full-scale test embankment reinforced with Tenax TT 201 polymer geogrids and weathered Bangkok clay as backfill material has been carried out. Finite element method has been employed to reanalyze all the measured data from the above test embankment. The agreement between the finite element results and the field data is quite good. The results indicate that the overconsolidation ratios affect much on the consolidation settlement. The consolidation has a strong effect on lateral displacement and strain of the reinforcement. The predicted results and measured data showed that the direct shear mode is suitable for large deformation and low stiffness reinforcements like Tenaxgeogrid. |
