Geotechnical centrifuges
The geotechnical research centrifuge is a 50g-tonne 4m diameter beam centrifuge, manufactured by Thomas Broadbent and Sons Ltd. Research focuses on themes of energy, hazards and infrastructure to engineer a more sustainable future.
About the centrifuge
The 1m diameter 'mini-beam' teaching centrifuge was developed as part of a Royal Academy of Engineering, National Higher Educational STEM Programme award in 2012. It is aimed at teaching and demonstrating the fundamental scaling laws and issues associated with centrifuge physical modelling across a range of ground and foundation engineering problems.
Physical modelling at prototype stresses can provide enhanced understanding of soil-structure interaction behaviour, under carefully controlled boundary conditions, leading to better geotechnical design and the development of innovative engineering solutions.
We can also make use of centrifuge scaling laws to uniquely investigate fundamental physical processes of fluid flow through granular media. This can enable accelerated timescales to be modelled compared to the field for continuum processes such as seepage in clay and the uncoupling of particle-fluid-pressure problems for processes such as seepage induced internal erosion.
Various model strong boxes are available, including both axisymmetric and plane strain “window” boxes for imaging at the side walls. Actuation, fluid injection, and a large range of sensors (eg PPT, loadcells etc.) and imaging cameras are available for testing in flight. Model preparation is assisted by automatic pluviation systems and consolidation rigs.
The small teaching centrifuge can also be used to examine research ideas at a preliminary stage. Small model containers are available to be used in a 'plug and play' mode for rapid testing.
