Sustainable usage of dredged clay materials as land reclamation fills. Millions of cubic metres of dredged materials are removed from river and sea beds every year in dredging projects. It is common to dump a significant portion of the dredged spoils into the sea which can result in serious environmental problems such as deterioration of water quality, damage to aquatic habitats, disruption of ecosystems and dispersion of fine clay particles in seawater. The proposed use of dredged clays as land ....Sustainable usage of dredged clay materials as land reclamation fills. Millions of cubic metres of dredged materials are removed from river and sea beds every year in dredging projects. It is common to dump a significant portion of the dredged spoils into the sea which can result in serious environmental problems such as deterioration of water quality, damage to aquatic habitats, disruption of ecosystems and dispersion of fine clay particles in seawater. The proposed use of dredged clays as land reclamation fill will lead to a substantial reduction in or even eliminate the need for dumping dredged clays into offshore dumping locations. The stabilized dredged clays have great potential if their geotechnical characteristics are adequately understood.Read moreRead less
Investigation of potential spudcan punch through failure. The safe and economic use of mobile jack-up structures is critical to the prosperous development of Australia's significant offshore oil and gas industry. However, their use is hindered by potential 'punch-through' failure during installation, when their large conical footings can unexpectedly and uncontrollably push a locally strong zone of soil into underlying softer material. To improve their safety, this research will investigate a po ....Investigation of potential spudcan punch through failure. The safe and economic use of mobile jack-up structures is critical to the prosperous development of Australia's significant offshore oil and gas industry. However, their use is hindered by potential 'punch-through' failure during installation, when their large conical footings can unexpectedly and uncontrollably push a locally strong zone of soil into underlying softer material. To improve their safety, this research will investigate a potential new site-investigation procedure and develop an appropriate calculation method for predicting failures for sites where sand overlies clay. Results will be based on a series of innovative physical and numerical experiments, and assessed against field data and existing industry standards.Read moreRead less
Study of Coupled Water-Gas-Sediment (three-phase) Flows through Jointed and Stratified Rock. Coupled Water-Gas-Sediment Flows through Rock Joints project outcomes are expected to surpass the current knowledge on ground/slope stability and water inundation, enhance engineering solutions of the associated problems and provide vital improvements to public safety. The research team will publish the research outcomes through peer-reviewed journals and conferences, nationally and internationally, rais ....Study of Coupled Water-Gas-Sediment (three-phase) Flows through Jointed and Stratified Rock. Coupled Water-Gas-Sediment Flows through Rock Joints project outcomes are expected to surpass the current knowledge on ground/slope stability and water inundation, enhance engineering solutions of the associated problems and provide vital improvements to public safety. The research team will publish the research outcomes through peer-reviewed journals and conferences, nationally and internationally, raising Australia’s scientific profile within the civil engineering and mining community. The Australasian Institute of Mining and Metallurgy and Institution of Engineers seminars will be organised to promote discussion with the practitioners while the Australian geotechnical community will gain expertise through the PhD program.
