Behaviour of Multi-layered Geocell-Reinforced Soil Embankment

Geocells are interconnected honeycombing geosynthetics used for strengthening the weak soil, pavement base/subgrade, embankment, etc. Considerable numbers of researches are performed; however, till date, an exact behaviour of geocell-reinforced soil is complex enough to predict. Modelling of geocell-reinforced soil, through numerical methods, is a difficult task because of its geometry and soil-reinforcement interaction; however, the modern FEM software are capable to provide considerably good estimate. This study, numerically, compares the behaviour of single and multi-layered geocell-reinforced embankment system with reference to study reported by Krishnaswamy et al. (in Geotech Test J 23:45–54, 2000) and Latha and Rajagopal (in Can Geotech J 44:917–927, 2007). It is observed a splitted (multi-layered) geocell system demonstrates improved performance compared to a single-layer geocell-soil composite of same thickness. In this study, a preliminary verification the concept is performed using PLAXIS2D simulating the work reported by Krishnaswamy et al. (in Geotech Test J 23:45–54, 2000). After satisfactory matching, it is further extended for multi-layer geocell system which is very encouraging for the concept envisaged.
