发明名称 METHOD FOR DETERMINATION OF AIR PERMEABILITY OF EARTH UNDER STATIONARY CONDITIONS
摘要 Method for determination of air permeability of earth includes sampling earth, bringing samples to air-dry state, weighting, filling cylinder with earth, passing air through earth under pressure. Air permeability is determined by fixation of air pressure in atmospheres or other units for measurement of pressure needed for surmounting resistance at its passage through earth layer.
