چکیده مقاله
The effect of reinforcement parameters i e , length, stiffness, and vertical spacing on the normalized differential settlements between geosynthetic reinforced soil GRS wall facing and reinforced zone was investigated in 34 short 8 m and 30 tall 20 m verified numerical models through finite element analysis The influence of retained soil type was also considered in the results Furthermore, the backfill soil was modeled using HS small constitutive model The results illustrated that increasing geogrid stiffness was the most effective method for reducing settlements in all short and tall models Increasing reinforcement length to values more than 0 8H had a minor effect on the normalized settlements Moreover, the normalized values of differential settlements and the effectiveness of vertical spacing of reinforcements were considerably different in short and tall GRS walls
