Long term stabilisation of expansive soils by polymer addition. Expansive soils can cause serious damage to infrastructure. The project aims to study the feasibility of reducing the long term swelling potential of expansive soils by polymer addition. The project involves advanced experimental testing to identify suitable candidates amongst different polymers and to test their long term performance.
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 novel computational methods for predicting failure rates in geographically distributed pipeline networks affected by ground movements, one of the main triggers of bursts and leakages in buried pipe infrastructure. The project will be based on a blend of experimental work and development of simulation tools to quantify the coupled effects of pipe deterioration, poor backfilling and ground movements in aged and new pipelines. The results will feed towards the formulation of a framework for the large-scale stress analysis of segmented and continuous pipes, capable of using as input high-resolution geospatial observations and predictions of ground movements.Read moreRead less

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

Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechani ....Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechanisms of mud pumping, incorporating train loads and frequencies, will be studied, and the role of vertically installed drains will be quantified for improved practical design. The project aims to contribute to improved track longevity and reduced maintenance costs, with a corresponding boost in rail productivity.Read moreRead less

In moving towards sustainable waste management, the Australian mining and steel industry is proactively seeking large scale recycling schemes for coal wash and slag. If the construction potential of these wastes is favourable for reclamation, then the environmental and socio-economic benefits will be substantial due to less quarrying of fresh rock and reduced volume of waste tips on otherwise usable land. The research outcomes will be published in peer-reviewed journals and conferences, raising Australia's scientific profile in granular waste management. The geotechnical community will benefit through the rigorous training of professionals, while industry hosted seminars will promote the dissemination of knowledge gained to practitioners.Read moreRead less
