Abstract

Abstract

A model was established for the study of ground vibrations generated by slab track that was subject to a unit force, the characteristics of slab track were considered, ground was modeled as a number of infinite-parallel-homogeneous-elastic layers overlying elastic half-space, the dynamic differential equations of the system were solved in wave-number domain, and then the vertical displacement amplitude of ground surface was obtained by implementing inverse Fourier transform.The applied result of the model shows that the dispersion characteristics of the vibrations propagating in ground can be demonstrated, the load speed has significant influence on ground vibrations, the spread scope and response amplitude of vibrations increase with load speed increase, Doppler effects occur when the speed is greater than Rayleigh wave speed, which indicates that the model can simulate the alluvial depositing stratification characteristics of ground.
