National rock, concrete and advanced composite testing capability:
The aim of the project is to develop a national hybrid biaxial/true triaxial load testing facility to serve the needs of geotechnical, structural, mining and materials researchers and engineers for sophisticated testing. It would address the need for leading edge testing and analysis of the deformation and strength of rock, concrete, and thin plates comprising metals, composites and polymers, under a wide range of loading conditions. The facility would accommodate cubic specimens up to 300 millimetres and be able to apply 10 megapascals of stress in up to three orthogonal directions. State-of-the-art monitoring equipment is designed to assess the degree of damage caused by testing, simulating damage induced by blasting, cutting, static loading and/or impact.Read moreRead less
Liquefaction of silty soils: Micromechanics, modelling and prediction. The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefac ....Liquefaction of silty soils: Micromechanics, modelling and prediction. The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefaction induced failure at the large scales. The expected outcomes are liquefaction criteria for silty soils with different silt contents and numerical tools to predict the onset of liquefaction and flow of liquefied soils.Read moreRead less
Impact of rolling dynamic compaction. The project will lead to improved understanding and greater use of rolling dynamic compaction (RDC). RDC is a relatively new compaction technique that can be used to improve soft and derelict ground prior to the construction of roads, railways, subdivisions and structures. This project will also lead to greatly reduced ground improvement costs.
Modelling rolling dynamic compaction. Modelling rolling dynamic compaction. This project aims to measure the influence and efficacy of rolling dynamic compaction (RDC)—a new ground improvement technology used worldwide—in soil types using RDC modules of different shapes and weights in an experimental testing facility. It will examine authentic 1:13 scale RDC models using sophisticated testing and instrumentation embedded in the soil, and use this data to develop a model based on artificial intel ....Modelling rolling dynamic compaction. Modelling rolling dynamic compaction.

It will examine authentic 1:13 scale RDC models using sophisticated testing and instrumentation embedded in the soil, and use this data to develop a model based on artificial intelligence techniques that reliably predicts ground improvement using RDC in different ground conditions. This research is expected to transform the Australian and global ground improvement sector, and save hundreds of millions of dollars in land development costs and infrastructure.Read moreRead less

Summary
The national geotechnical centrifuge facility. A new geotechnical centrifuge will enable the modelling of complex offshore and onshore structures. The new facility will support many geotechnical fields, associated with the economical and geographical development of Australia, and ensure that Australia will maintain its leadership within the international physical modelling community.
The role of vegetation and associated root suction and reinforcement on the stabilisation of transport corridors and sloping ground. The project will promote the concept of green corridors and green hills for stabilising unstable soils through optimum root reinforcement and suction. The improved load capacity, control of unacceptable soil movement and slope stabilisation will provide an efficient platform for sustainable development of transport and building infrastructure.
Predicting the foundation performance of offshore jack-up drilling rigs in intermediate soils. The research outcomes will be a major step forward in creating safer operations of mobile platforms in our challenging seabed conditions. The new models and guidelines will assist engineers in the efficient expansion of our offshore oil and gas industry, with significant increased investment projected over the next five years.

The research is using innovative physical and advanced numerical modelling techniques to quantify the significant increase in sand resistance caused by rapid penetration, enabling reliable design and reducing risk of material failure associated with the high impact forces. Expected outcomes of the project include a conceptual framework and scientific-based design tool to predict the geotechnical performance of offshore installations. The research will provide the necessary scientific advances to install, moor and service offshore wind and wave energy devices more economically and efficiently.Read moreRead less
Foundation systems for reactive soils using scarification and screw piles. This project will investigate the use of soil scarification, in combination with screw piles, as a reliable option for light-weight foundations on damaging reactive (expansive) clay soils. It will validate an innovative foundation alternative that will result in significant cost savings for residential foundations on reactive soil.

Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems as excavation, fragmentation, earthquake, blasting, and structure design. In geotechnical and structure projects, materials are often subjected to existing confining stresses. The full-field optical techniques, with an ultra-high speed and resolution camera in the system, aims to assist the quantitative measurement of deformation fields including small strain induced in brittle material's failure and identification of constitutive parameters.Read moreRead less
