The Geotechnical laboratory comprises approximately 2500 square feet and supports small-scale physical modeling and material testing for determining the characteristics of geotechnical materials. The laboratory houses two temperature-controlled chambers; one for material testing at elevated or sub-zero temperatures, one for sample storage. The laboratory is also equipped with a workshop and a range of equipment for material testing. This testing includes: grain size analysis, triaxial testing (standard, high temperature, high pressure), hydraulic conductivity testing (flexible wall, suction control), oedometers, standard direct shear apparatus, a large-scale direct shear/pull-out apparatus, a thermal needle probe, and an erosion measurement device.
Software is available for 3D, 2D and axisymmetric finite-element modeling of soil with respect to stress and deformation analysis, groundwater flow and seepage, slope stability, and thermal behaviour.
