In this paper, the fractal characteristics of fissurestructure in expansion soil are studied based on fractal theory.
依据分形理论，研究了膨胀土裂隙结构的分形特征，分析了膨胀土裂隙网络分维和裂隙面分维的力学效应。

The pressurized mercury fissures were high. The fissurestructure and the adsorption borehole were in overwhelming superiority and were taking 78 % of the total fissure value.
压汞孔隙度较大，孔隙结构以吸附孔占绝对优势，约占总孔隙含量的78%；
