The characteristics of Love wave induced by vehicle loads are of tremendous importance to both dynamic response of structure and exploration of the soil profile. Analytical method is applied to construct the displacement distribution equation and the dispersion secular equation of Love wave generated by vehicle loads in two-layered ground. The dispersion characteristics and displacement distribution of Love wave under various loads are discussed. The results prove Love wave induced by vehicle loads is different from the Love wave induced by other loads; the properties of Love wave generated by vehicle loads are not only related to the thickness

mass density and shear wave velocity of the layer soil

but also related to compression wave velocities in soil.
