Physical Models for Experiential Learning in Geotechnical Engineering

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.
