摘 要: :分析了膨胀土结构的分形行为 ,推导了膨胀土颗粒粒度的分维、颗粒质量的分形、孔隙分布的分维、孔隙表面分维计算公式 ,并结合实例进行验证 。 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.
关 键 词: 膨胀土结构 颗粒粒度 孔隙比 孔隙表面 路基稳定
