Abstract
Considering the effect of atmosphere, the natural permeability variation process of expensive soil is simulated by lab test. The method of Fredlund & Xing is also used to predict the permeability coefficient of unsaturated expensive soil. The results show that drying-wetting cyclic action may increase the permeability of expensive soil, which illuminates the atmosphere influence depth evolution of cut slope. The results can supply parameter reference in design and numerical calculation.
