Abstract:

Rough terrains were prepared using quartz sand with six average particle sizes in a mini-size bin. A special instrument equipped with distance laser sensor was used to collect the digital information of the surface morphology of the rough terrains, and analyze the pretreated data. The fitting curves of the average Root Mean-Square (RMS) height and the average terrain energy as functions of the mean particle size, the physical meaning of the areas enclosed by the frequency axis and the auto power spectrum density curves indicate that the average terrain energy and the terrain roughness have obvious relationship. Thus, the terrain energy can be used to analyze the terrain roughness quantitatively. The analysis of the linear fitting result of the double logarithmic auto power spectrum density curve shows that the slope of the linear fitting line increases with the terrain roughness. It proves the reliability of using the relative positions of linear fitting lines and the slopes to evaluate the roughness of the terrain.

Key words: road engineering, terrain roughness, terrain energy, auto power spectrum density, distance laser senor
