Session: Professional Practice/Case Studies

ABSTRACT: Physical models constructed to support experiential learning of geotechnical concepts are utilized by Algonquin College students enrolled in the Bachelors of Building Science program. This paper describes a model used to visualize the effective stress theory and to introduce the concept of vertical stress profiles. Another physical model highlighted in this paper consists of a scaled model of a pump test in an unconfined sand aquifer. These physical models support experiential learning styles where the students are actively involved with their in-class experience. The models also provide a practical basis for discussion and analysis of geotechnical topics such as soil liquefaction, slope stability and bearing capacity of soils. When demonstrated in class, these models deliver both visual and tactile evidence of fundamental principles in soil mechanics. The models support the application of experiential learning methodologies to assimilate theory by active experimentation.

RÉSUMÉ: Les étudiants inscrits au programme de Baccalauréat en science du bâtiment au Collège Algonquin utilisent des maquettes pour accompagner l'apprentissage expérientiel des notions de base de la géotechnique. Cet article présente une maquette utilisée pour visualiser la théorie de la contrainte effective et comme introduction au concept du profil de la contrainte Ces maquettes soutiennent une pédagogie active par laquelle les élèves sont directement impliqués dans leur apprentissage en classe. Les maquettes fournissent également une plateforme concrète pour la discussion et l'analyse des notions de base en ce qui a trait à la liquéfaction des sols, la stabilité des pentes et la capacité portante du sol. Lors de leur utilisation en classe, ces maquettes fournissent des exemples visuels et tactiles des notions de base de la la théorie par une expérimentation active.
