Abstract:
In order to clear the reinforced structures' deformation law caused by creep of geosynthetics, the reinforced embankments under different working conditions were analyzed with finite difference method. The deformation of reinforced embankment caused by the creep of geogrid was presented. Three aspects, such as the settlement distribution on the top of the embankment, horizontal displacement of the embankment caused by the creep of geogrid, and geogrid strain were analyzed. The results show that the settlement distribution on the top of the embankment, the horizontal displacement of embankment, the geogrid strain have positively proportional relations with the height of embankment, and have inverse proportion relations with slop rate and elastic modulus of geogrid. 3 tabs, 6 figs, 10 refs.
