This project aims to develop new knowledge on the performance of battered minipile systems used in a wide range of applications from solar panels to traffic signs. Minipiles provide concrete-free foundation systems, yet their behaviour under more complex loading such as wind, is yet to be fully understood. This project will examine the loading conditions experienced during installation and throughout service life. This will include complex full-scale laboratory tests and advanced computer modelling to verify the performance against expected cyclic loading. New design approaches will be developed for this emerging foundation system, enabling more widespread adoption of this technology in the building and construction industry.Read moreRead less

Braced batter micropile group: New design theory and performance framework. This project aims to research the design and performance of innovative biomimetic braced battered micropile group footings. This project will test Surefoot, the new concrete free footing, in the laboratory, in the field, and through numerical and analytical modelling. Surefoot’s mechanisms of action are poorly understood but clearly more complex than current micropile theory; this project will research the mechanism of load transfer from micropiles to the soil and soil response.Read moreRead less
Modelling and simulation of complex granular flows. Granular flows are of crucial importance in a wide range of problems related to civil infrastructure. These include landslides and similar catastrophic events, often leading to loss of life and property. The project aims to develop new methods for accurate prediction of such events thus allowing for the formulation of efficient mitigation strategies.

Summary
Selective laser melting - an advanced manufacturing and physical modelling technology for the digital age. Selective laser melting is a new manufacturing technology that creates parts layer by layer directly from a computer model, eliminating the need for tooling or machining. This technology will be applied to a diverse range of research areas from producing the next generation of medical implants and devices to improving our understanding of geo-materials.
Accurate Prediction of Safe Life of Buried Pipelines. Failures of buried pipes are disastrous, causing severe consequences and disruptions. They often reoccur because the fundamental cause-effect relation for pipe failures has not been fully understood and hence the safe life of pipelines cannot be reliably predicted. The aim of this research is to develop a new theory to predict pipe failures, based on a fundamental analysis of pipe behaviour and failure mechanisms and a reliability approach.

They often reoccur because the fundamental cause-effect relation for pipe failures has not been fully understood and hence the safe life of pipelines cannot be reliably predicted. The aim of this research is to develop a new theory to predict pipe failures, based on a fundamental analysis of pipe behaviour and failure mechanisms and a reliability approach. The outcomes will be a suite of models and solutions that will advance knowledge in deterioration science and failure theory. They will provide a sustainable solution to the intelligent management of buried pipelines throughout the world.Read moreRead less

This project aims to develop a technique to accurately predict the remaining safe life of deteriorated buried stormwater pipelines, thereby preventing their catastrophic failure. The research also aims to advance knowledge in deterioration science of reinforced concrete and failure theory of buried pipes. The outcomes are anticipated to be a suite of rational, practical and validated models for pipe deterioration as measured by crack growth and residual strength which are integrated in a time-dependent reliability method and coded as a computer program ready for take-up by end-users. Preventing catastrophic failures of buried pipes should deliver economic, environmental and social benefits.Read moreRead less
Non-differentiable Energy Minimisation For Modelling Fractured Porous Media. 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.

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 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
Dynamics analysis of unsaturated porous media subject to damage due to cracking. This project relates to rigorous analysis of dynamic response in unsaturated soils. It will lead to cost savings in many geotechnical engineering practices as it will provide a better understanding of the behaviour of unsaturated soils to dynamic loading and a greater confidence in the prediction of the performance of earth-structures.
