Conductivité hydraulique non saturée de l'argile de Mers El Kébir (Algérie)
This paper presents hydraulic conductivity measurements carried out on unsaturated Mers El Kebir clay, from Algeria, using the vapour equilibrium technique. The principle is to measure the water exchanges between the sample and the environment under a relative humidity imposed by saturated salt solutions, to establish the relationships between hydraulic conductivity, water content (w), degree of saturation (Sr) and suction (uc). Samples are initially compacted to the standard Proctor optimum water content and maximum density and used as such and after saturation or drying. Drying-wetting paths were also performed in order to compare the direct hydraulic conductivity measurements to the values derived from Fredlund et al. (1994) and Mualem (1976)-van Genuchten (1980) models.
