- FUNCTIONAL MODELS TO PREDICT AIR PERMEABILITY COEFFICIENT FROM WATER CHARACTERISTIC CURVE OF UNSATURATED SOILS
抄録
For predicting the air permeability coefficient from the water characteristic curve of unsaturated sandy and silty soils, the applicability of the air permeability model based on the Burdine theory and Mualem theory for expressing the relationship between the air permeability coefficient and the degree of water saturation is examined. As a result, the model based on the Burdine theory is more applicable during the drying process. However, the optimized parameter ξ-values for pore tortuosity in the models are varied for each soil and related the shape of the water characteristic curve. And then, it is recognized that the both models are good agreement with each other and fitted to the measured air permeability coefficient.
