Stabilization of Steep Slopes on Soft Foundation Using Geocells
Geocells are three-dimensional honeycomb shaped geosynthetic material used for ground improvement. It is mainly used for strengthening foundation beds, flexible pavements and for erosion control. In the case of steep and high slopes, it is necessary to provide reinforcements to ensure the stability of structures. In places where foundation is made up of soft soil, foundation reinforcement becomes necessary. Geocells are usually provided in the form of basal reinforcement. Geocells can provide confinement and tensile strength which can help in increasing the factor of safety of slopes. Present study indicates the efficacy of geocell in the stabilization of a lateritic steep slope resting on a clay foundation. Numerical modeling was conducted using a commercially available software PLAXIS 3D. An attempt of modeling of the curvilinear geometry of geocells was done and validated. Slope stabilization using geocell in the form of slope reinforcement and also as a foundation reinforcement was presented in this study. The slope was found to be stable when geocell was provided both as foundation reinforcement as well as along the slope (GCFS) owing to the site conditions, slope geometry, and soil properties.
