The performance of an embankment on soft ground reinforced with geosynthetic and floating pile walls system

The design of embankments on soft ground requires the safety against potential bearing capacity failure, global slope instability, local failure, large total and/or differential settlements, and large lateral movement through the stages of embankment construction. Horizontal geogrid reinforcement combined with floating pile walls can provide an effective solution to ground improvement to support high embankments. This paper demonstrates the results of numerical analysis to study the performance of embankment on soft ground in the north coast of Egypt near Dumyat City, and the effect of inclusion of horizontal reinforcement of geogrid layer and vertical floating pile walls. The numerical results show that a combination of geogrid reinforcement and the floating pile walls is very effective for the improvement of soft ground and the stability of the embankment.
