Abstract

Reinforced pile embankments are
started use more commonly because they allow fast construction of highways. When
geosynthetics are adopted to piled fills, this kind of structures are then
called as geosynthetic reinforced piled structures. When the geosynthetics are
used, area of pile caps is reduced because geosynthetic transfers fill load to
piles by its membrane effect. In this study, effect of multi – layer
reinforcement is investigated using 2D finite element method. For this purpose,
settlements, pressures, excess pore water and horizontal displacements are
analyzed. Results showed that using two and three layers of reinforcement significantly
decreases settlements on foundation soil and embankment surface. Placement of
additional layer has great effect on settlements, pressures, excess pore water
pressure and horizontal displacements. It is also found out that, two layers of
reinforcement is more effective when only settlements are considered.
