| Abstract | Full scale embankment of rubber tire sand mixture with geogrid reinforcement and vertical precast concrete facing was constructed on soft clay with a total height of 6.0 meter at AIT campus. In this study, the behavior and predicted the settlement and excess pore pressure of the embankment was monitored after construction. The maximum pore pressure occurred at 1 to 2 days after construction, the maximum average excess pore pressure were 55 kPa and 48 kPa corresponding to 3.0 m and 6.0 m depths, respectively. The excess pore pressures build up during loading seemed to occur at a very quick rate according the predicted of exceed pore pressure and subsequent dissipation afterwards. The maximum lateral outward movement of the wall face occurred at the top, 125 mm after 210 days after the end of the construction. The maximum tension line of geogrid reinforcement observed that is Rankine failure plane of extensible reinforcement. The averages of surface settlements on ground are 111 mm. The averages of subsurface settlement at 3.0 m and 6.0 m about 100 mm 80.5 mm, respectively. The degree of consolidation of the soft subsoil foundation during the same period was 62. 72% by using Cv from Asaoka's method. The predicted settlement on ground from Asaoka's method agreed well with the field monitoring from full-scale embankment test. From pullout test results, the maximum pullout resistance in the laboratory are slightly similar test by Prempramote, 2005. However, The laboratory pullout tests yielded peak pullout resistances at relatively low displacements of the geogrid reinforcement obtained trend to interaction parameter. |
