| Abstract: | The geotechnical materials mostly show fractal distribution, and they have self - similar or scale invariability. Using the theory of Fractal Geometry, the fractal dimension characteristics of fine soil granularity distribution before and after dynamic compaction is studied by analyzing soil granularity of Century Park in azhuang City, Hebei Province. The engineering significance of fractal dimension is discussed further. |
