摘要：
To obtain the road excitation, 3D walking pavement of transportation vehicles was reconstructed based on fractal characteristics in theoretically. The random samples were generated by inverse Fourier transform of international and national standard pavement spectrum, the average fractal dimension (1.59) was calculated using the Contour RMS method; 3D pavement theoretical model was established according to the average fractal dimension and the statistical characteristics of 2D standard pavement by the Random mid-point displacement method and the Triangulations method; every grade pavement was simulated in 3D space, vertical section of which could be regard as 2D standard simulation pavement. This method is fit for 3D reconstruction of pavement.
