The saturated hydraulic conductivity of undisturbed soil can represent the really case in the field and is significant to study soil moisture balance and soil water conservation.
The results of the undisturbed soil showed decrease in both cohesion and internal friction angle occurred by wetting, while little change in the strength parameters was observed for the remolded soil.
The study results indicate that there is a soil liner shell outside the mortar liner shell, and the shear strength of the soil liner is obviously higher than the undisturbed soil.
The grain size analysis and microstructure observation of the undisturbed soil samples from both sides of the road were made, and the fractal theory was used to analyse the soil sample.
