ABSTRACT: Problematic soil is divided into dispersive, swelling, and collapsible soil. The latter is the most common type of problematic soil which can be found in vast areas of Okanagan valley. Present study is mainly focused on predicting the collapse potential and analyzing the properties of collapsible soil throughout two case studies. In each case, the collapse potential was obtained in three different ways (densometer, Gibbs theory, and consolidation machine) and compared with each other. This paper has proved that in all case studies the collapse potential of soil measured through different methods are in agreement with each other. Moreover, the collapsibility of the soil is highly dependent on wet density of the soil in a way that samples with lower wet density will face higher collapse.
RÉSUMÉ: Les sols problématiques sont divisés en sols dispersifs, gonflables et vulnérables à la rupture. Ce dernier est le type le plus répandu des sols problématiques qui peut être trouvé dans de vastes régions de la vallée de l'Okanagan. La présente étude est principalement axée sur la prédiction de la rupture potentielle et sur l'analyse des propriétés du sol vulnérable à la rupture à partir de deux cas étudiés. Dans chaque cas, l™effondrement potentiel a été obtenu de trois manières différentes (densitomètre, la théorie de Gibbs, et la machine de consolidation). Dans les deux cas et quelques soit la méthode utilisée, l™effondrement mesuré est en accord. En outre, l™effondrement du sol dépend grandement de la densité humide du sol, de manière que les échantillons ayant une faible densité humide devront subir des effondrements plus spectaculaires.
