| Abstract: | In order to evaluate the effect of rail traffic vibration on the production and living activities of people,we set up a calculating model of half-space body of visco-elastic free field under moving concentrated harmonic load,and studied its related law of vibration by means of Fourier transform and its inverse transform and Green’s function,giving out the calculating expression of the ground vibration velocity and obtaining the general law of vibration of visco-elastic free field under moving concentrated harmonic load by analyzing the change trends of vibration velocities with different influence factors. |
