Course overview and goals

Geo-materials have complex mechanical properties with a lot of influential factors, which cause complicated behaviors of geotechnical structures such as foundations, slopes and tunnels. Physical modeling using scaled models under clear initial and boundary conditions is one of the effective approaches to observe the behaviors and study the influence of critical factors.
This course instructs theory, requirements, technology needed in physical modeling of geotechnical problems such as the scaling laws, appropriate simplification, sample preparation and measurement of the soil behaviors.

Course description and aims

Through lectures and group works, the students acquire fundamental knowledge of physical modeling in the field of geotechnics such as scaling laws for various geotechnical problems under static and dynamic loading conditions, simplification in model construction, soil preparation methods, measurement strategy, loading techniques.

Keywords

properties of geo-materials, scaled models, scaling law, sample preparation, measurement strategy and sensors, static problems, dynamic problems, group work
