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.

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. This project will develop new cost-effective methods for designing against rock fall events using a combination of advanced testing and computer modelling.Read moreRead less
Influence of tunnelling on pile foundations. The effects of tunnel construction on the behaviour of existing pile foundations will be investigated. In particular, models will be developed to predict the influence of tunnel excavation on the bearing capacity, average settlement, differential settlement and tilt of pile groups and the loads and bending moments induced in the piles of the group and the pile cap. These models will allow rational assessment of the effects on buildings undermined by ....Influence of tunnelling on pile foundations.

These models will allow rational assessment of the effects on buildings undermined by tunnels. This work is significant and timely because of the growing trend to place transport infrastructure underground in many cities of the world.Read moreRead less
New design guidelines and simplified analysis methods for geosynthetic reinforced pile-supported embankments. There is a growing demand in Australia for efficient technologies for soft soils due to increasing infrastructure development on marginal land characterized by soft ground. One such technology that is becoming popular is geosynthetic reinforced pile-supported embankment as it requires less land, construction time and maintenance.

There is a growing demand in Australia for efficient technologies for soft soils due to increasing infrastructure development on marginal land characterized by soft ground. One such technology that is becoming popular is geosynthetic reinforced pile-supported embankment as it requires less land, construction time and maintenance. The outcomes of this research will lead to cost-effective and reliable infrastructure design of benefit to the many future infrastructure projects, totalling billions of dollars, planned for Australia. This project will therefore contribute significantly to the sustainability of our environment and increase the international competitiveness and export potential of the Australian construction industry.Read moreRead less
Application of expanded polystyrene (EPS) geofoam and deep cement mixed columns for protection of existing foundations during urban construction. Urban construction activities are increasing in the capital cities of Australia, and the occurrence of new construction activities near existing structures is increasing. The main outcome of this project will provide economic engineering strategies for the protection of buildings during urban construction activities, hence minimising construction relat ....Application of expanded polystyrene (EPS) geofoam and deep cement mixed columns for protection of existing foundations during urban construction. Urban construction activities are increasing in the capital cities of Australia, and the occurrence of new construction activities near existing structures is increasing. The main outcome of this project will provide economic engineering strategies for the protection of buildings during urban construction activities, hence minimising construction related damage, litigation and delays as witnessed recently during Sydney's Lane Cove tunnel collapse. Proposed novel solutions using EPS geofoam and deep cement mixing will significantly increase the international competitiveness and export potential of the Australian construction industry, and improve community confidence in developers and the Engineering profession.Read moreRead less

The aim of this project is to undertake a fundamental study of the mechanical behaviour of structured soils in order to formulate appropriate constitutive models. This work is significant because it will contribute to the progress of soil mechanics as a science, advancing it from the study of reconstituted laboratory soils to that of real soils. The project should ultimately lead to cost savings in many geotechnical engineering practices because it will provide a better understanding of the response of real soil to loading, and provide greater confidence in predictions of the performance of geotechnical structures.Read moreRead less
Mechanics of partially saturated soils and Its applications. The project aims to study the fundamental behaviour of Australian natural soils under varying water contents and loading conditions. Some immediate applications include the design of foundations on reactive soils and the analysis of rainfall-induced landslides. In both cases, the aim is to improve the design method and hence reduce the damage cost.

This project aims to develop and validate a new, robust and cost-effective method for geotechnical hazard assessment of rock slopes. Each year in Australia, millions of dollars are spent on stabilising unstable slopes and mitigation measures to control the associated risk and avoid severe financial impacts. The proposed framework will combine a new qualitative approach for geotechnical hazard assessment with accurate, efficient geo-structural surveys achieved with emerging surveying technologies. Stochastic components of slope geostructural description should minimise the surveying operations. This project is expected to reduce the cost and time of surveying geostructural features of slopes and designing mitigation measures.Read moreRead less

This project aims to develop an accurate and efficient simulation framework that allows the consideration of realistic discrete behaviour in geomechanical models without the computational overheads of current models. 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
