A laboratory device to analyze the behavior of pile-supported embankment reinforced by geosynthetics

Pile-supported embankment on soft soil are currently reinforced by geosynthetics. Many an-alytical methods have been developed to design the geosynthetic but they are simplistic and do not take into account all the complexity of the developed mechanisms. Despite all the difficulties met when simu-lating the behavior of pile-supported embankments in the laboratory, it is shown that 1g physical modeling tests can help one to understand the behavior. A new small-scale model, which has been developed to reproduce the behavior of pile-supported embankment at the scale 1/10. A specific study have been made to find and qualify a foam simulating the behavior of the soft soil. The first tests have validated the ability of the device to correctly simulate the behavior of pile-supported embankment.
