Analytical approach to determine FoS of geocell-reinforced slope using HSM
{Geocell reinforcement- geocell + infill soil} modelled as a composite beam filled with soil
Improvement in FoS of geocell-reinforced slope:
In terms of- vertical stress dispersion, vertical frictional resistance, and structural mechanisms
Hoop tension theory: used to compute effect of geocell pocket diameter on soil confinement and
FoS of geocell-reinforced slope
Numerical Modelling using SRM: comparison of results of proposed analytical model
Parameteric analysis: to evaluate the influence of

on the stability of geocell-reinforced slope
Results: shows reinforcing mechanism of geocell reinforcement is related to geocell thickness. The
mobilized flexural strength and vertical frictional resistance magnify as height of geocell increases.
Compared with planar reinforcement, a smaller quantity of geocell reinforcement is required to
achieve an equivalent FoS value.
