Abstract

Abstract

In order to investigate the dynamic strain responses of rigid pavements subjected to moving constant load and harmonic variation load, pavement was regarded as a plate with infinite extent on a viscoelastic foundation, formulations of moving loads were developed in time-space transform domain by using triple Fourier transform, and the effects of viscous damping, vehicle speed and load on the strain were studied. Experiment environment was simulated by using five embedded strain sensors, pavement dynamic strain response was measured, and measure result was compared with simulation result. Comparison result shows that the responses of rigid pavement to vehicle velocity and viscous damping are larger, the response induced by constant load is less than the response induced by harmonic load, and the response induced by harmonic load is a little larger than experimental result.
