This project aims to develop a predictive model for the macroscopic behaviour of clay by combining direct observations of microscopic and mesoscopic mechanisms with rigorous physical principles. The project expects to track clay aggregates as they expand or shrink under variable loads and moistures using novel X-ray and optical methods. A key anticipated result is the development of a robust hydrodynamic model for clay that rationalises the observed phenomena. Expected outcomes include the accurate predictions of clay dynamics, either fast during landslides or slow under drying and wetting. As much of Australia experiences droughts and floods, this project should benefit the longevity and safety of critical infrastructure situated on clay.Read moreRead less

This project will reduce the cost of offshore floating wind energy by uniting leading academic expertise and innovative industry partners to develop the knowledge and practical tools that will enable the deployment of helical anchors as a cheap and reliable anchoring system for floating wind. Helical anchors are seen as the most promising solution to anchor wind turbines, but their deployment has been limited by uncertainties associated with the torque and vertical force required for installation in complex seabeds, and their performance under environmental loading. The project will address these specific points through a combination of physical, numerical and analytical modelling, using data and design scenarios provided by industry.

This project is aimed at advancing theoretical, computational and experimental bases for the fracturing of geomaterials, and providing scientists and engineers with much needed predictive tools for quantitative assessment of the responses. By incorporating previously neglected aspects such as energy minimisation, advanced constitutive modelling, and non-planar interacting fracture growth, confidence in the design and planning of engineering processes in fractured porous media will be increased to the point that costly over/under designs are avoided. Through the use of the tools developed, it will be possible to detect weaknesses in the design, assess the impact and implement effective measures to improve performance.Read moreRead less
Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will dev ....Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will develop tools, models and theories to detect weaknesses in the design of infrastructure and its foundations built on problematic reactive soils, assess the impact and implement effective remedial measures to improve performance. The project is expected to increase efficiency through improved design and reduced damage, and save infrastructure owners, government and private, tens of millions of dollars each year.Read moreRead less

Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be ca ....Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be catastrophic. By establishing an improved understanding of internal erosion as a sequence of processes on various scales, from the onset of erosion until the failure of the structure, this project will place Australia at the forefront of dam safety assessment.Read moreRead less

New computational methods and open-source simulation tools will be developed which will enable the efficient and accurate dynamic simulation of large-scale problems in geomechanics, problems that had formerly been intractable because of their computational size. The unique combination of discrete and continuum methods will allow the economical solution of a range of important geotechnical problems such as the accurate prediction of dynamic effects due to tunnelling, underground workings and mining activities. The outcomes will lead to safer and more economic construction methods and a more accurate assessment of the environmental effects.Read moreRead less
