Transforming decision making for rockfall hazard assessment. The aim is to transform conventional approaches to rockfall hazard prediction and mitigation. The management of risks posed by rockfall in Australia currently comes at significant cost and is suboptimal; predicted environmental changes are likely to worsen these hazards. Rockfall mechanics, remote sensing, and data-driven modelling will be combined with advanced visual technologies to deliver a novel, rapid, and reliable augmented real ....Transforming decision making for rockfall hazard assessment. The aim is to transform conventional approaches to rockfall hazard prediction and mitigation. The management of risks posed by rockfall in Australia currently comes at significant cost and is suboptimal; predicted environmental changes are likely to worsen these hazards. Rockfall mechanics, remote sensing, and data-driven modelling will be combined with advanced visual technologies to deliver a novel, rapid, and reliable augmented reality based rockfall hazard assessment tool. The outcomes are expected to streamline prediction, assessment, and mitigation – supporting practitioners and governments to proactively assess triggering conditions, evaluate risk, and apply robust solutions to improve safety, with substantial economic savings.Read moreRead less

This project aims to develop the mechanics of geosynthetic-reinforced flexible pavements as an urgent need for the Australian pavement industry to build more sustainable and economical roads. Novel laboratory test apparatus and in-situ test programs, and mathematical models will be developed, for the first time, to capture the responses of reinforced base courses in a complete and optimised way to determine the parameters for pavement design and performance evaluation. The outcomes will enable reliable prediction of reinforced pavement behaviour, leading to better-performing geosynthetic products and more resilient pavements, reduced material usage and damage in pavements, and less environmental impact and maintenance cost.Read moreRead less

A multi-scale theory for solid-granular transition due to fragmentation. The prediction of rock fragmentation and fragment sizes during its phase transition from solid (rock mass) to granular (ore fragments) is the most crucial problem in a cave mining operation. Current practice relies on empirical tools without fundamentals of fracture, and hence cannot reliably predict the fragmentation process and fragment sizes. This can lead to huge economic loss due to damage to extraction points, hold-up ....A multi-scale theory for solid-granular transition due to fragmentation. The prediction of rock fragmentation and fragment sizes during its phase transition from solid (rock mass) to granular (ore fragments) is the most crucial problem in a cave mining operation. Current practice relies on empirical tools without fundamentals of fracture, and hence cannot reliably predict the fragmentation process and fragment sizes. This can lead to huge economic loss due to damage to extraction points, hold-ups for safety precautions, and mine closures. The project will develop a new theory and models to describe this solid-granular transition, and computational tools for simulations of cave mining operations. The expected benefits and outcomes include safer operations, and better control of production schedule and budgeting.Read moreRead less

Summary
Bridging the gap between rockfall theory and engineering practice. Fragmentation is often observed post rockfall events and it is recognised as a critical aspect of adequate rockfall risk management. Yet, rockfall fragmentation is a complex phenomenon still poorly understood and not properly considered in engineering practice. This project aims at developing a theoretical and stochastic fragmentation framework, based on high-quality and comprehensive experimental data, in collaboration with lead ....Bridging the gap between rockfall theory and engineering practice. Fragmentation is often observed post rockfall events and it is recognised as a critical aspect of adequate rockfall risk management. Yet, rockfall fragmentation is a complex phenomenon still poorly understood and not properly considered in engineering practice. This project aims at developing a theoretical and stochastic fragmentation framework, based on high-quality and comprehensive experimental data, in collaboration with leading international industry partners that provide advanced geotechnical design tools to practitioners around the world. The outcomes of the project will bridge the gap between rockfall theory and engineering practice. It will allow for more cost-effective and safer design of rockfall protection structures.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.
