WA Symposium 2021
Geotechnics in Mining & Infrastructure
Doug Stewart, Ruth Stephenson, Yuxia Hu and James Jung
The Western Australia (WA) Chapter of the Australian Geomechanics Society (AGS) is pleased to announce a one-day symposium titled “Geotechnics in Mining & Infrastructure” which is to be held on 15 October 2021. The symposium will be held as an in-person event in Perth, forming part of the continued program of events organised by the AGS WA Chapter. It aims to keep the engineering industry informed of recent geotechnical advances in mining and infrastructure industries, as well as challenges and opportunities.
Western Australia’s mining and construction industries are currently booming with growing investments in public infrastructure and mining projects. Geotechnical engineering forms a crucial foundation for the success of these industries. This symposium will present overviews of current state of-the-art practices, innovation and new research relating to geotechnical engineering within mining and infrastructure environments.
The symposium will bring together Western Australian professional engineers, researchers, specialist contractors, regulators, educators, and students to share and discuss their experiences in mining and infrastructure geotechnics.

About the speakers
Doug Stewart is a Principal of Golder Associates, with 35 years’ experience as a geotechnical engineer mainly based in Perth, Western Australia. He has worked as the main geotechnical consultant, reviewer or advisor on a large number of major construction projects, including rail tunnels, underground structures, road, rail and public infrastructure, projects on soft soils, high-rise buildings and multi-level basements.
His experience includes 12 years in research/academic roles at The University of Western Australia and University of California, Davis. He has a PhD in Geotechnical Engineering, with his research project on lateral loading of piled bridge abutments due to embankment construction on soft soils funded by Main Roads WA.
Ruth has worked in the mining industry since 2003 initially as a geologist, then as a geotechnical engineer since 2006. She spent the first nine years working in underground mines throughout Western Australia. Since 2012 Ruth has worked at AMC as a consulting geotechnical engineer, a role which has taken her further afield and expanded her experience to international projects and open pit mines. Ruth was also active in the local geotechnical community in the role of secretary of the Western Australian Ground Control Group for six years. Ruth is now a director of AMC and manager of the geotechnical group in AMC’s Perth office.
Prof. Yuxia Hu obtained her PhD degree in 1991 in costal and offshore engineering. After graduation, she has been working in China, Japan and Australia. After she joined the Geomechanics group (later Centre for Offshore Foundation Systems – COFS) at the University of Western Australia (UWA) in 1992, she started to work with Prof. Mark Randolph to develop the LDFE/RITSS (Large Deformation FE/Remeshing and Interpolation Technique with Small Strain model) method for solving soil-foundation interaction problems involving large deformations of soils in offshore applications. The LDFE/RITSS method has been implemented in different commercial software and applied to many offshore soil-structure interaction problems successfully. Her current research covers two areas: (i) offshore foundations for renewable energy explorations; and (ii) using recycling resources in pavement designs. Prof. Hu has published more than 100 journal and conference papers on improving offshore foundation designs, and corresponding design guidelines. Her contribution to the geotechnical community has been recognised by 2005 IACMAG Junior/Senior Paper Award, 2006 BGA Best Paper Award and 2018 ICE Telford Premium Award. Her research in recycling resources in pavement designs involves collaborations with state government, local governments and pavement engineers to build our sustainable future. Prof. Hu is currently the Head of Department of Civil, Environmental and Mining Engineering at UWA
