‘Scaled Physical Modelling of Geotechnical Structures and Processes in the Centrifuge’

Centrifuge modelling is an advanced physical modelling technique for simulating and studying geotechnical problems and processes. It provides experimental data for investigating generic mechanisms of deformation and failure, for validating analytical and numerical methods, to predict the behaviour of full-scale structures and for design applications. Due to its reliability, reduced testing time and cost effectiveness, centrifuge modelling has often been the preferred experimental method for addressing complex geotechnical problems. In this seminar, the kinematics, fundamental principles and principal applications of geotechnical centrifuge modelling are introduced. The new state-of-the-art geotechnical drum centrifuge being commissioned at Western University will be described in detail. The differences between beam and drum centrifuge technology will be discussed. Centrifuge modelling of a range of different geotechnical problems will be presented with the major findings and new insights found from these tests. New developments such as an earthquake actuator, fluid wavemaker, bender element array and soil model formation systems will be described. The overall aim of the talk is to illustrate the role of centrifuge modelling in advancing our scientific knowledge of geotechnical engineering.
