The Statistical Analysis of Gravel Soil Permeability Coefficient of the Three Gorges Reservoir Area

Abstract:

According to the Geological Diversity and Soil Characteristics in the Gorges Reservoir Area, the Statistical Analysis was Carried on the Content, Grade, Porosity and Permeability Coefficient (PC) of Gravel Soil, Respectively. the Value of Saturated Permeability Coefficient (SPC) is up to 10-3. the Value of the Total SPC is that Zigui is the Highest, Badong-Fengjie Area is Less than that in Zigui, and it is the Lowest in Fengjie-Chongqing Area in its Distribution. the Relationship between the Montmorillonite (MMT) Content, Stone Content, the Uneven Coefficient and PC are all Positive. the Curvature Coefficient and Void Ratio are all Negatively Correlated with PC. these Data Showed the Relationship between the Index of Material Composition and PC of Gravel Soil.
