Research Projects

Current projects

Quantitative structural health assessment of large membrane-like structures

This project aim to develop a new approach, based on remote sensing and computational modelling, to assess and manage the structural health of large floating covers to prevent its unexpected failures. This project will address the impediments that are plaguing current state-of-the-art structural health monitoring and inspection techniques. A successful completion of the present project would clearly provide a superior alternative to the current hazardous walk-around inspection used by Melbourne Water, and a sound basis for identifying early indications of distress or of potential failure. The project has potential benefits for high-value-added manufacturing and maintenance of these floating covers by Australian industry.

SA water cast iron pipe testing

Development of Fibre Optic based sensors for critical road railway, port, bridge and pipeline monitoring

Failure probability prediction implementation to improve Sydney Water's renewal program for critical water pipes

This project forms part of the implementation plan commissioned by Sydney Water (SW) to utilise and validate the developments in Advanced Condition Assessment Pipe Failure Prediction (ACAPFP)project in particular failure probability prediction for two cohorts of pipes in the SW network. The intention is to demonstrate through these selected areas how SW can apply the developed knowledge and develop the required tools to implement it across the entire SW network

Preventing reoccurance of catastrophic failures of stormwater pipelines

This research will develop an innovative technique to accurately predict the remaining safe life of deteriorated buried stormwater pipelines, thereby preventing their catastrophic failures. The research will advance knowledge
in deterioration science of reinforced concrete and failure theory of buried pipes. The outcomes will be a suite of rational, practical and validated models for pipe deterioration as measured by crack growth and residual strength
which are integrated in a time-dependent reliability method and coded as a computer program ready for take-up by end-users. Preventing catastrophic failures of buried pipes will bring about economic, environmental and social
benefits – both nationally and internationally.

Development of advanced deterioration model for the design of stabilised pavement bases

Some 95% of 900,000 kms roads in Australia are made of unbound granular materials. Majority of these roads have aged significantly and traffic loads and frequency have increased markedly. Road stabilisation by in-situ recycling of old pavement materials using cementitious additives is commonly used as an option with lower environment footprint. The main failure mode of stabilised pavements is by fatigue cracking. Unfortunately, current design methods against fatigue cracking are unsatisfactory and do not take into account key operational factors. This project intends to undertake a bottom-up scientific study to significantly advance the design methods and associated testing of these pavements potentially leading to large cost savings.

A multi-scale approach to investigate desiccation cracking in clayey soils

Soil desiccation cracking can adversely affect the stability and effective performance of many vital geoinfrastructures. For instance, desiccation cracks have contributed to a number of dam and slope failures incurring significant damages. Despite its importance, our understanding of the mechanism of drying shrinkage cracking and ways to control or avoid such cracking in soils are 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 will lead to new sophisticated
continuum models for reliable prediction of soil desiccation cracking in many applications.

Past projects

The National Geotechnical Centrifuge Facility

Soil behaviour is stress dependent and requires enhanced gravity levels to ensure correct scaling between large geotechnical structures and small laboratory models. A geotechnical beam centrifuge, 10 m in diameter and capable of rotating 2400 kg of soil at 100 g, will provide Australia’s outstanding geotechnical research groups, including the recently established ARC CoE for Geotechnical Science and Engineering, with world leading physical modelling capabilities. The national facility will underpin Australia’s energy, mineral and transport infrastructure developments, estimated at $250B over the next five years, through accurate model testing of offshore foundations, slopes, tunnels, mine wastes and ground improvement techniques.

Advanced Condition Assessment and Failure Prediction Technologies for Optimal Management of Critical Pipes ("Critical Pipes")

Non-contact strain prediction for the structural health monitoring of large membrane-like structures

National Facility for Cyclic Testing of High-speed Rail (FCTHSR)

Frontier technologies in rail transport demand access to state-of-the-art testing facilities for track modelling.
The proposed National Facility for Cyclic Testing of High-Speed Rail (FCTHSR) is internationally a first-of-its kind and it will be designed and built in-house for examining an array of Australian ground conditions and integrated track components. This unique facility will offer a national and international hub for industry-driven research and consulting. The project outcomes will propel more Australian researchers to be among the world-leaders of rail technologies providing better solutions to challenging track environments. Prototype testing will ensure safer and cost-effective track designs.

Smart Sensor Technology for Pipelines

Advancement of cohesive crack approach to model shrinkage and load induced cracking in multi-phase soils

Cracking in clay soils is a major issue in civil, environmental agricultural and resource engineering sectors. Cracks in soil structures and systems can occur due to external loading or due to internal matrix shrinkage or as a combination of both. Comparatively, this issue has received less attention in the past and the associated knowledge gaps hinder the progress of these disciplines. It is also recognised that the impending climate change will influence the severity of soil cracking affecting greatly the performance of surficial or shallow- buried geo-infrastructure. This proposal will address this issue through new theoretical developments, innovation of testing and numerical techniques and evaluation of climate change effects.

Developing engaging, effective and enlightening practical experiments in geotechnical engineering

A National Facility for In situ Testing of Soft Soils

A crawler mounted in situ soil testing laboratory capable of accessing soft and swampy sites will provide Australia’s outstanding geotechnical research groups, including the ARC CoE for Geotechnical Science and Engineering, with state-of-the-art field testing facilities. The equipment is essential to the research of these groups as it will provide real data on the behaviour of soft soils for the development and calibration of theoretical design models. It will facilitate the development of the next generation of in situ testing devices and lead to improved interpretation of test results. This research will advance the design of infrastructure, such as roads and railways, which are increasingly being routed across soft estuarine deposits.

Prediction and controlling of pipe failures in buried water and gas pipe systems

Australian buried water and gas pipe networks extend over hundred thousand kilometres. As these pipe systems age, pipe failures have also increased, leading to wastage of valuable commodity and increasing social and economic costs to the community. Effective pipe asset management tools are urgently needed to maintain reliable and safe supply of these essential services. There is clear evidence that pipe failures are significantly related to soil behaviour influenced by seasonal climatic conditions. The current asset management models do not adequately consider these issues. This project will develop methodologies for predicting and controlling the failure of buried water and gas pipes for effective pipe asset management.

FLAC Module for two phase flow

Advanced Testing Facility for Geological Sequestration of Greenhouse Gases

A facility for the analysis of geological materials and their geo-thermal-mechanical interactions with complex fluids (such as carbon dioxide CO2, water, methane) is required to support a large number of research projects in high priority areas including geological sequestration of greenhouse gases and oil/gas recovery at three different leading Universities. The unique features of the proposed facility are that it is capable of analysis large samples, under multiple forms of loading and over a range of high pressures and temperatures. This will enable us to do proper design, management, and optimisation of subsurface CO2 sequestration operations for safe storage of CO2 in geological formations.

Modelling of shrinkage crack development in porous media

Spectacular cracking patterns can develop in porous materials as they shrink during drying or cooling. The cracks can compromise the material integrity and can provide speedy pathways for water and contaminant migration.This is a pressing problem in a diverse range of fields involving geotechnical, geo-environmental, agricultural, geological, mining and material applications. Because of poor fundamental understanding and lack of reliable predictive methods to control cracking, this problem is a stumbling block for engineers and scientists. The investigator proposes an innovative approach to solve this problem using elasto-plastic fracture mechanics, with potential for far-reaching benefits.

Stabilization of railway subgrade by lime-flyash slurry injection

The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key parameters involved in the improvement of subgrade soil by injecting lime-flyash slurry. This project will develop an improved design procedure for lime-flyash slurry injection in the field based on experimental and numerical modelling.

Subsea Pipelines Cluster - Structural Integrity

Hydro-mechanical interactions in coal geo-sequestration of carbon dioxide

Geo-sequestration of carbon dioxide (CO2) is considered the most promising technology to reduce atmospheric release of CO2. The storage of CO2 in deep unmineable coal deposits has many advantages that include: a high storage capacity, high permeability, and the release of methane, a valuable resource. However, there is considerable uncertainty regarding the impact of CO2 on the mechanical properties of the coal. This project aims to reduce these uncertainties by experimental investigations of the transport of CO2 through coal, and the effects this has on the mechanical properties. The data will be used to develop new coupled numerical models that will be used to investigate the procedures required for successful sequestration.

Influence of scale effect on the strength of rock mass for the better prediction of slope stability in large open-cut mines

The research project will concentrate primarily on understanding the mechanisms of slope failure in large and deep open cut mines with the goal of developing improved assessment criteria for designing rock slopes. Mechanisms governing shape, location and propagation of slope failure surfaces are highly dependent on insitu and induced stresses, strength of rock mass, and induced pore water pressure. Accurate determination of rock mass strength and their use in slope stability analysis will enable mining engineers to develop improved slope design methodologies which will enable them to enhance the safety of the mine workers and to reduce lost time and increase the production.
