Research projects using instructional geotechnical centrifuge


An instructional centrifuge is fabricated based on the instructional centrifuge at the University of Colorado at Boulder. The UVM centrifuge is equipped with a loadcell and displacements are obtained through analysis of digital images of the models.   A large consolidometer (20 cm in diameter) is also fabricated to prepare large consolidated clay cakes for making centrifuge models. The centrifuge is used to conduct educational research projects on the following stability problems: (1) undrained slope stability (validation of Taylor’s stability chart and limit equilibrium-based computer program SLOPE/W); (2) retaining wall (Rankine’s active and passive earth pressure theories); and (3) undrained bearing capacity (validation of Prandtl’s bearing capacity theory).
