The finite element method is used to simulate the orbital structure, and the finite element model of "rail - sleepers - ballast" can be established. The model of the elastic modulus of different ballast and sleeper is calculated, and the rail displacement, the sleeper stress and the fastening force are deduced. The results show that the elastic modulus of the ballast can be increased to reduce the displacement of the rail and the supporting force of the fastener, but the stress of the sleeper will be increased. When the modulus of elasticity increases, the rail displacement, small.
