A testing study of variation in permeability of unconsolidated soil under saturation

Based on the engineering geological characteristics of purple rock or soil in the reservoir area of the Three Gorges,the changes in river level are considered and undisturbed soil samples are collected from surface layers of the Shiliushubao landslide in the Huanglashi landslide groups.Taken the undisturbed soil samples as a subject of investigation,a running water-saturated experiment is designed.Under the condition of soil sample saturated in running water,the permeability of purple-unconsolid...
