Abstract
ABSTRACT In this paper, geosynthetic reinforced granular fill-soft soil system subjected to a moving load with constant velocity over an infinitely long beam is analyzed. The foundation is assumed as tensionless foundation (to react only in compression). The upper reinforced granular bed is modeled by a rough elastic membrane embedded in Pasternak shear layer overlying a series of compressible Winkler springs representing the underlying soft soil. The parametric studies reveal that the flexural response of the infinite beam as well as of the reinforcement, are greatly affected by the velocity, intensity of load and compressibility of granular fill. The interfacial frictional coefficients, shear modulus of granular layers and coefficient of lateral earth pressure do not significantly affect the response of the beam and the reinforcement for the range of parameters studied.
