Abstract: The problem of soil deformation under moving load is discussed in this paper. The calculation formulas for soil deformation under different load forms are obtained.Taking rectangular load as an example,the effects of track,load frequency, load velocity and soil model on the soil deformation are compared.This method can be used to evaluate the environmental vibration induced by rail system.
