Permeability tests are one of the most often performed experiments in geotechnics. Conventional methods conducted by oedometer and triaxial apparatus have many disadvantages, the most significant being the test duration. As a consequence, errors in permeability measurements could occur. On the contrary, ...

A simple technique is proposed in this paper for estimating the coefficient of permeability of an unsaturated soil based on physical properties of soils that include grain size analysis, degree of saturation or water content, and porosity of the soil. The proposed method requires the soil-water ch...

Development and verification of a coefficient of permeability function for a deformable unsaturated soil The modelling of flow through saturated/unsaturated soils has become routine in geotechnical and geo-environmental engineering. The analysis requires that ... Shangyan Huang, , S L Barbour, and , ...
This paper introduces a new method——"in-situ permeability test" used in saline soil, and gives out an equation of the coefficient permeability measurement according to mathematical model. The validity of the method and the formula have been examined by the practice. The results can be also re...
This permeameter can accommodate a large tailings specimen, 200×200×400mm high, and uses the Instantaneous Profile Method (IPM) to determine the variation of unsaturated coefficient of permeability with respect to soil suction using a single specimen. The soil-water characteristic curve data can ...
