Membrane Effect of Geogrid Reinforcement for Low Highway Piled Embankment under Moving Vehicle Loads

In this paper, the membrane effect of geogrid reinforcement was investigated based on numerical simulation to understand serviceability and deformation highway piled embankments under moving vehicle loads. The in low (i.e., ratio embankment height pile spacing is less than 1.5) clearly emphasized. It has been found that maximum settlement occurs central area between piles, tension concentrated at corner cap. Due attenuation soil arching dynamic loads punching mechanism, increased considerably by approximately 35% 23% compared those static A parametric study also achieved, results presented increasing spacing, stiffness, wheel load velocity. most sensitive among all parameters considered whose magnitude 104% as from 2.0 m 2.5
