Professor Randolph is internationally recognised for his outstanding fundamental contributions to foundation and offshore engineering that have found wide application in civil engineering and offshore projects. A feature of his work has been the development of simple and practical solutions to complex problems. Examples include: expressions for the elastic response of pile foundations under loading; plasticity solution for the flow of soil around pipelines; the analysis of drag anchors and novel designs for piled raft foundations and he has pioneered the development of geotechnical centrifuge modelling in Australia.
