Leading Research in Geomechanics

The PRCGSE focuses on the development of innovative test procedures, field monitoring techniques, mathematical models, and computational methods to predict the behaviour of soils, rock and other materials.By linking two of Australia’s leading research teams, namely the Geotechnical Research Group and Diffusion in Solids Group, the PRCGSE is uniquely equipped to study a range of problems with length scales that vary over several orders of magnitude. The outcomes of this research are delivering improvements in the safety, efficiency and reliability of civil infrastructure and mechanical technology.

The PRCGSE is currently conducting research in five key areas:
