摘要：
Accurate measurement of air permeability through partially saturated soils in the laboratory requires a system capable of measuring permeabilities using both low and high driving pressures. This is evident when one considers that the air permeability of a clayey-soil specimen can change many orders of magnitude depending on the water content of the specimen. © ASCE.
