خلاصه مقاله:
Geocell can be used as a reinforcement to increase bearing capacity of a soil foundation and reduce itssettlements due to its cellular structure. A generalized analytical model is presented for determination offooting settlement on a subgrade soil idealized as a linear elastic layer. The geocell layer could beconsidered as a beam. A forth order ordinary differential equation (ODE) is derived and solvedaccording to appropriate boundary conditions using Laplace transform. The results have a wellcoincidence with available data published in the literature. Parametric studies have then been performedto demonstrate the effect of contributing parameters such as modulus of subgrade reaction, geocell layerwidth and height and geocell mattress shear modulus on footing response.
