【Abstract】 The fractal behavior of structure of expansive soil is analysed in this paper, and the fractal behavior of graded aggregate, substance, pore ratio, pore specific surface of expansive soil are also inferred, and they are demonstrated in a case study, the analysising result would be useful to stability study of expansive soil in railway foundation.更多还原
