Abstract

Geocell can be used as a reinforcement to increase bearing capacity of a soil foundation and reduce its settlements due to its cellular structure. A generalized analytical model is presented for determination of footing settlement on a subgrade soil idealized as a linear elastic layer. The geocell layer could be considered as a beam. A forth order ordinary differential equation (ODE) is derived and solved according to appropriate boundary conditions using Laplace transform. The results have a well coincidence with available data published in the literature. Parametric studies have then been performed to demonstrate the effect of contributing parameters such as modulus of subgrade reaction, geocell layer width and height and geocell mattress shear modulus on footing response. Keywords: Geocell reinforcement, Laplace transform, Analytical solution, Closed form formulation
