A New Western Geo-Centrifuge Opening Symposium 2019

Date: May 2 & 3, 2019

Location: Western University, London, ON, Canada


Western University in Canada is having an official opening and international symposium to celebrate the commissioning of a new state-of-the-art Western Geotechnical Centrifuge (2.2m drum type centrifuge). The event will take place in the Department of Civil and Environmental Engineering at Western University (London, Ontario, Canada) on Thursday and Friday, May 2-3, 2019. The official website is https://www.eng.uwo.ca/wgc/ .

The event is planned to celebrate the commissioning of a new Western Geotechnical Centrifuge Facility in the Department of Civil and Environmental Engineering at Western University. The opening and a tour of the facilities will take place on Thursday, May 2, 2019, from 11 a.m – 12:30 p.m. This will be followed by an international symposium on geotechnical centrifuge technology on the afternoon of Thursday, May 2 and throughout Friday, May 3, 2019.

During this symposium, seven international keynote speakers will exemplify the use of centrifuge technology in geotechnical engineering. In addition, several Western researchers will provide an overview of the state-of-the-art techniques being developed in the new facility. This event will showcase the use of scaled physical modelling for geotechnical design, construction and practice across a range of industry sectors. There will also be ample opportunity to discuss possibilities for future research during the event.

Location: Western University, Geotechnical Research Centre, Department of Civil and Environmental Engineering, Spencer Engineering Building and Amit Chakma Engineering Building, London, Ontario, Canada.

Western Centrifuge Information

New drum centrifuge in Western University

Due to the complexity of many geotechnical processes, the analysis and prediction of most engineering phenomena requires a mathematical description or simplified ‘model’ of behaviour that incorporates only the most salient features of the behaviour.

This is precisely what Western University is striving to do through the construction of a 2.2m drum centrifuge facility, which will be fully commissioned by the summer of 2019. Dr. Tim Newson, one of Western’s acclaimed research directors, is currently leading the $5.5M Canada Innovation Fund (CFI) grant proposal. Entitled, ‘Enhancing the Resilience and Sustainability of Critical Geotechnical Infrastructure’, this project will bring together the combined expertise of geotechnical researchers at nine Canadian universities.

The centrifuge facility will provide crucial geotechnical data and predictive models that will enable the development of safe, economical and robust geotechnical structures and processes in Canada. This data can be used to improve our understanding of basic mechanisms of deformation and failure, provide benchmarks useful for verification of numerical models and enable the development and optimization of design and construction methods. The main focus of the work will be the long-term behaviour of geotechnical structures and the development of resilient and sustainable geotechnical solutions able to cope with accumulating damage over time.

The centrifuge is distinguished by its ability to carry a payload around the entire circumference of a large rotating drum. The rotation of the centrifuge permits the scaled physical modeling of geotechnical processes and structures up to 400 times Earth’s gravity, allowing researchers to simulate in-situ or self-weight stresses that exist in a variety of scenarios or problem types.

The centrifuge is particularly suited to modeling long or large single geotechnical structures or processes. Consequently, the initial work will involve the study of components of large public infrastructure, including shallow and deep foundations; pipelines and slope; and underground structures for transportation, utilities and wastewater networks. The centrifuge can also be used to simulate a long construction site with soil that has a common geotechnical or geological history. Therefore, the centrifuge enables behavioural comparisons for a range of different structures, as well as the replication of tests in the same material.

The addition of novel actuators will also provide a unique modelling environment that can simulate the effects of earthquake loading, cyclic two degrees of freedom loads and displacements, and large fluid waves on geotechnical structures. Essentially, centrifuge modelling permits the simulation of processes that would otherwise be highly time consuming, extremely difficult or even impossible to safely conduct, such as long-term consolidation problems, explosions or contaminated waste studies.

From parametric studies used to identify trigger mechanisms, interpret observations and confirm hypotheses, to the validation of theories and calibration of analytical and numerical techniques, the potential applications of this new state-of-the-art facility for geotechnical research are far-reaching.
