Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 139 N° 2 (Février 2013) . - pp. 320-329 Titre : Probabilistic porous model to simulate the retention curve of soils Type de document : texte imprimé Auteurs : Eduardo Rojas, Auteur ; Jaime Horta, Auteur ; Teresa López-Lara, Auteur Année de publication : 2013 Article en page(s) : pp. 320-329 Note générale : geotechnique Langues : Anglais (eng) Mots-clés : porous  media;  stochastic  models;  soil  suction;  pore  size  distribution;  unsaturated  soils Résumé : A probabilistic porous model is used to simulate the retention curves of different types of soils. The model is based on the same principles of porous networks models; however, it shows important advantages over them. It considers two different elements: the sites and the bonds. It is able to simulate the retention curves of a material when its pore size distribution is known. It can also be used to interpret more realistically the results of mercury intrusion porosimetry tests. In this paper, the model is used to obtain the pore size distribution of different soils using the retention curve as its data source. The comparison between numerical and experimental results for different soils shows that the model approximately reproduces the pore size distribution obtained from mercury intrusion porosimetry tests.
