In modern society of highly development of transportation

the environmental vibration induced by rapid rail transit has set off more and more close attention and researches.Vibration responses of typi- cal sites in Nanjing city induced by rapid rail transit are analyzed with the software ABAQUS.Based on the load model of irregularly track geometric condition and the nonlinear dynamic visco-elasto-plastic con- stitutive model of Davidenkov skeleton curve of the soils

the responses of ground surface vibration with different train speeds for typical sites in Nanjing city are analyzed to obtain the frequency character of vi- bration and acceleration intensity of ground surface vibration as well as their attenuating law

which are basic data to further research on the control of ground surface vibration induced by rapid rail transit.
