摘要: The dynamic displacement and stress responses of a plate infinite extent on viscous Winkler foundation subjected to moving tandem-axle loads with amplitude variation have been investigated. Formulations developed in the transformed field domain using triple Fourier transform time, space, space for arbitrary variation, double steady-state response harmonic loads. rigid flexible pavement systems selected as models foundation. effects damping, load velocity, frequency, phase between front- rear-axle maximum deflection distributions near analysis results considering viscosity show significant differences from those obtained an elastic system. caused by surface roughness difference can make considerably larger.
