Method for determining the air permeability of water-conducting soils, and a system and devices for carrying it out

摘要

Method for determining the air permeability of water-conducting soils, in which by injecting specific amounts of air per unit of time at one or more spatially distributed points and at the greatest depth of the spatial and three-dimensional region of the soil formation to be investigated, the flow of air inside this spatial and three-dimensional region is determined by subsequent measurement of the ascertainable air and air pressures inside the circumferences of the injection points at measuring points which are arranged staggered in terms of depth and space.
