Abstract: PURPOSE:To facilitate the computation of water permeability coefficients in a short time by laminating a sample to be measured with measuring samples whose permeability coefficients are larger than that of said sample, forming a test body, making water permeate into the test body, and measuring a unit quantity of permeation. CONSTITUTION:A test body having a laminated structure is formed on a stage seat 11 at the bottom of a pressure-proof container 1 with the following materials: a sample to be measured whose thickness is thin and permeability coefficient is unknown, and measuring materials 2 and 21 whose permeability coefficients are known and larger than that of the sample 3. Then water is infiltrated into the test body from a water feeding tank 61. The unit quantity of water permeation in a measuring buret 72 is measured through a water pipe 7. The unit quantity of water permeation, the unit cross sectional area of the test body and a unit hydraulic grade are substituted for the terms of the equation of the Darcy's law. Thus the permeation coefficient of the entire test body is computed. Then, the permeation coefficient of the sample to be measured 3 is obtained based on the permeation coefficient and the thickness of the entire test body, the thickness of the sample to be measured 3 and the permeation coefficients of the measuring materials 2 and 21.
