Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects.

Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can considerably benefit from the findings of this project including safer structures, significant reduction in the future maintenance costs and enhancing the performance of bridges, buildings, roads, railways and dams with less cracks and differential settlement.Read moreRead less
Geotechnical characterisation of compacted ground based on passive ambient noise techniques. The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available.

The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available. The project will help steer Australia to the forefront of ambient noise research for geotechnical site investigation, in the characterisation of unsaturated compacted soil and in the determination of dynamic site characteristics which are required for seismic risk assessment. Two postgraduate students will benefit from this research by receiving research training at the highest level and it will also pave the way for exporting the technology developed overseas, particularly to our near neighbours in Asia and the Pacific.

Behaviour of Tunnels in Sedimentary Rocks of the Sydney Basin. The aim of this project is to gain understanding of ground behaviour around tunnels in the Sydney region, how the ground interacts with fibre reinforced shotcrete tunnel linings, and how changes in material performance affect risk to users and the reliability of the tunnel structures. These aims will be met by a combination of field and laboratory experiments and theoretical modelling. The outcome will be a rational and reliable de ....Behaviour of Tunnels in Sedimentary Rocks of the Sydney Basin.

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
Combining transient micro-reflections and multi-sensor arrays for condition assessment of buried pipes. This project will develop an accurate and reliable approach for assessing the condition of pipelines. This new approach will reduce costs and save considerable amounts of water each year, as it will assist utilities in preventing major failures such as pipe bursts, and performing strategically targeted maintenance, replacement and rehabilitation.
High-strength formwork systems. The project will lead to new formwork systems which are safer, stronger and quicker to erect. The systems will rely on scientific investigations to minimise the risk of structural collapse and associated cost to community.

Barriers for cost - effective rock fall hazard mitigation. Rock fall barriers are used throughout Australia to protect its extensive road and rail networks. These networks are vital links in the nation's infrastructure and underpin its economic prosperity and development. There are thousands of cuttings on Australia' transport networks, many of which have the potential to be affected by rock falls. These events can take lives and severely disrupt the performance of our transport infrastructure. ....Barriers for cost - effective rock fall hazard mitigation.
