| Abstract | A full scale reinforced earth embankment was designed and constructed by Departm ent of Highway (DOH) of Thailand on a hard foundation in Phitsanulok province . There were two types of reinforced earth embankment. One side was reinforced with polymeric reinforcement s consisting polyester (PET), Polypropylene (PP) and high density polyet hylene (HDPE) and referred as reinforced steep slope (RSS), which is at 70 degree s from horizontal. In the other side , embankment was reinforced with metallic reinforcement s consisting metallic strips (MS) and steel wire grids (SWG) combined with precast c oncrete panel and termed as mechanicall y stabilized earth wall (MSEW). The b ehavior of a reinforced soil slope (RSS) and mechanically stabilized earth wall (MSEW) on hard foundation were observed and compared with the simulated result s from PLAXIS 3D soft ware . The lateral displacements and settlements were very small in case of MSEW facing consisting of steel wire grid (SWG) and metallic strip (MS). O n the other hand, the RSS deform much more due to their lower stiffness. The comparisons of these reinforci ng materials in terms of stiffness from highest to lowest are metallic strip (MS), steel wire grids (SWG), polypropylene (PP), high density polyethylene (HDPE) and polyester (PET). The results obtained from 3D finite element method simulation (PLAXIS 3D) h ave good agreement with the field measurement s in terms of vertical and lateral de formations and s trains in the reinforcements . Moreover, the verification of modified K - stiffness method was also performed. The results indicated that generally the modified K - stiffness method can be applied for reinforced embankment on hard foundation |
