Analysis of Interlock-Enhanced Integral Geocell-Reinforced Foundation

This study analyzed the mechanism of a new interlock-enhanced integral geocell (IEI geocell)-reinforced foundation using FEM3D. The vertical displacement, horizontal displacement, and stress distribution in the soil were studied. The tensile stress, friction, and contact force of the IEI geocell strips were also investigated. The IEI geocell reinforcement layer was found to reduce the horizontal and vertical displacements. The confinement of the IEI geocell is mainly attributable to friction between the infill material and the IEI geocell wall. The stiffness of the IEI geocell offers a tensioned membrane effect and broader stress distribution, resulting in better performance of the soil foundation.
