Abstract

The paper presents a model for the analysis of granular foundation beds reinforced with several geosynthetic layers Such reinforced granular beds are often placed on soft soil strata for an efficient and economical transfer of superstructure load The granular bed is modeled by the Pasternak shear layer and the geosynthetic reinforcement layers by stretched rough elastic membranes The soft soil is represented by a series of nonlinear springs The reinforcement has been considered to be extensible and it is assumed that the deformation at the interface of the reinforcements and soil are same The nonlinear behavior of the granular bed and the soft soil is considered Plane strain conditions are considered for the loading and reinforced foundation soil system An iterative finite difference scheme is applied for obtaining the solution and results are presented in nondimensional form The results from the proposed model are compared to the results obtained for multilayer inextensible geosynthetic reinforcement system Significant reduction in the settlement has been observed when the number of reinforcement layer is increased In case of inextensible reinforcements as the number of reinforcement layer is increased the settlement is decreased with a decreasing rate but in case of extensible reinforcement the reduction rate is almost constant Nonlinear behavior of the soft soil decreases as number of reinforcement layer is increased The effect of the stiffness of the geosynthetic layer on the settlement response becomes insignificant for multilayer reinforced system but the mobilized tension in the reinforcement layers increases as the stiffness of the geosynthetic layers increases
