Abstract: The paper presents the feasibility of conducting insite permeability testing to evaluate the seepage of the saline soils in western Qinghai. The concept of permeability coefficient is also introduced in the paper. The grain size characteristics of the saline soils in Mangya and the selection of the testing equipment for the insitu seepage testing are also introduced. The test points at various soil depths and soil properties are characterized. The permeability tests procedures and the seepage volume with time curves are provided. The seepage limits in the saline soils are evaluated by the high density resistivity method.

Key words: Seepage Testing, High Density Resistivity Method, Coefficient of Seepage
