Abstract: In this paper the spouting permeation method and equations are presented for determing permeability coeffcient K by the way of pressure water test. The parameters can be obtained by means of non-steady flow under the condition of certain confined extent and direction.The theoretical formula is deduced by analyzing two types of pressure water test, with outlets one at the tube terminal and another at tube circumference.K is calculated from the records of electrical resistance.q-T-R curve is finally obtained and a contradistinction with K determined by means of traditional steady flow method is listed.
