Özet:

The railway track has a non-uniform wavy geometry in the horizontal and vertical planes, as seen in the graphs produced by track geometry recording cars. The roughness of the track geometry can be expressed numerically using fractal dimensions if this geometric structure is considered a fractal pattern. In this study, fractal analysis method was used to determine the geometric roughness of the Ankara-Eskişehir High-Speed Railway track. A calculation algorithm based on the ruler method was used to calculate fractal dimensions. Fractal dimensions are calculated for alignment and longitudinal level graphs. According to the calculations, it has been determined that the general unevenness of the line geometry can be expressed numerically with the fractal dimension. At the end of the study, the relationship between the standard deviation of geometric parameters, which are indicators of track quality, and fractal dimensions, was investigated. Accordingly, there is a strong relationship between the proposed fractal dimension and the standard deviation.
