Abstract

In the present paper, soil-structure interaction analysis of an infinite beam resting on extensible geosynthetic reinforced earth beds has been carried out for an applied load moving with constant velocity. The viscous damping of the soil-foundation system has been given due consideration in the analytical procedure. The infinite beam has been treated as resting on a granular fill layer overlying the naturally occurring weak soil layer. Geosynthetic layer has been provided in the granular fill layer and has been considered as extensible. This extensible nature has been incorporated with the help of no slip and the compatibility conditions at the interface between reinforcing layer and the neighboring soil. These conditions help in eliminating the two interfacial shear stress parameters and in considering the tensile modulus of geosynthetic layer in the analysis. The influence of various parameters, like magnitude and velocity of applied moving load, viscous damping, relative stiffness of granular fill and tensile modulus of geosynthetic layer, on the response of soil-foundation system has been studied. It has been observed that all these parameters affect the response significantly, however, the effect of velocity of moving load and viscous damping has been found to be more significant especially at higher velocities.
