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.
Development of advanced deterioration model for the design of stabilised pavement bases. The Australian road network is a lifeline infrastructure that underpins the nation's living standards and economy. Much of these roads have deteriorated and require rehabilitation to get a new lease of life. This project intends to develop advanced methods to extend the lives of these pavements using in-situ recycling of old pavement materials.

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
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.
A multi-scale approach to investigate desiccation cracking in clayey soils. The project plans to develop a model of the mechanism of drying shrinkage and associated cracking in soils. Soil desiccation cracking can adversely affect the stability and performance of many vital geo-infrastructures. For example, desiccation cracks have contributed to dam and slope failures incurring significant damages. Our understanding of the mechanism of drying shrinkage cracking and ways to control or avoid such ....A multi-scale approach to investigate desiccation cracking in clayey soils. The project plans to develop a model of the mechanism of drying shrinkage and associated cracking in soils. Soil desiccation cracking can adversely affect the stability and performance of many vital geo-infrastructures. For example, desiccation cracks have contributed to dam and slope failures incurring significant damages. Our understanding of the mechanism of drying shrinkage cracking and ways to control or avoid such cracking in soils is not yet fully developed. This project aims to advance knowledge of the nature of crack initiation and propagation in clayey soils induced by moisture evaporation, through the use of advanced experimental and modelling techniques. Outcomes are expected to lead to new continuum models for reliable prediction of soil desiccation cracking.Read moreRead less
Large-scale geotechnical analysis of new and aged pipeline infrastructure. 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.

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
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

Proper understanding of soil-water interaction is vital for sustainable development of floodplains, and to halt acid mine drainage caused by the oxidation of pyritic soil. Permeable reactive barriers (PRB) offer a cost-effective solution to neutralize acidified groundwater. The project aims to quantify the clogging potential of PRB’s granular medium by coupling geotechnical fundamentals with integrated hydro-bio-geochemical processes. Time-dependent clogging will be evaluated through geotechnical laboratory & field testing.
