Experiment Research and Design of a Field Test Device for Permeability of Pore Air of Unsaturated Soils

Abstract:

Permeability of pore air is one of the main basic characters of unsaturated soil. Measuring it accurately is important in anti-seepage design. In this paper, a new kind of device was invented that could test permeability of pore air of unsaturated soil in situ quickly and accurately. With this apparatus, the relationship of air permeability coefficient with various dry densities and saturation of ground soils were obtained in a reservoir. Compared with routine indoor test, field test can decrease the disturbance to the soil and the result is more accurately.
