Modelling of beams on a geosynthetic-reinforced granular fill–soft soil system subjected to moving loads Available to Purchase

This paper presents an analytical method for a geosynthetic-reinforced granular fill–soft soil system subjected to a load, moving at constant velocity, over an infinitely long beam. The upper reinforced granular bed is modelled by a rough membrane embedded in a Pasternak shear layer overlying a series of compressible Winkler springs representing the underlying soft soil. Parametric studies reveal that velocity, load intensity and compressibility of granular fill have significant effects on both the flexural response of the infinite beam and the reinforcement. In contrast, interfacial frictional coefficients, shear modulus of granular layers and coefficient of lateral earth pressure do not affect the response of the beam.
