Permeable reactive barriers are passive subsurface installations that remove contamination from groundwater as it flows through a reactive substrate. This project will develop new permeable reactive barriers that will benefit the nation by building skills and knowledge in an area of growth in Australian industry, namely the rehabilitation of industrial lands and the protection and remediation of Australia's critical groundwater sources. The project is aimed at remediating an industrially contaminated site in the Hunter Valley, New South Wales, thereby contributing to the environmental improvement of that region. The technology developed will have wide application to other sites, both nationally and internationally.Read moreRead less

Summary
Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation.

Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After validation using experimental data and numerical simulations, the proposed analytical model can be used to mimic soil behaviour more closely than traditional models, thereby leading to more realistic settlement predictions.Read moreRead less

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less

Engineering the strength and consolidation of reclaimed soft soil. This project aims to strengthen reclaimed soft soils by controlled desiccation. Soft soil is a significant engineering challenge for many industry sectors in Australia and worldwide. The disposal of dredged soft soil is costly and time-consuming, and failure of soft mine tailings is an environmental catastrophe that can cause loss of life and interrupt mining production. This project will research the underlying processes of material behaviour, by developing new electromagnetic measurement and modelling methods to predict material strengths at the micro and macro scales during desiccation. The new approach is expected to lead to innovative solutions to bearing capacity and settlement problems associated with soft soils.Read moreRead less

A new approach for characterising soils based on electric parameters. This project aims to develop a predictive methodology based on electromagnetic sensors to quantify soil state variables that influence hydraulic and mechanical processes. These processes affect the safety of man-made and natural geo-structures such as dams or embankments. Conventional monitoring methods are outdated and unreliable, reducing our capability of detecting threats to these structures.

This project aims to develop a predictive methodology based on electromagnetic sensors to quantify soil state variables that influence hydraulic and mechanical processes. These processes affect the safety of man-made and natural geo-structures such as dams or embankments. Conventional monitoring methods are outdated and unreliable, reducing our capability of detecting threats to these structures. The outcomes of the project will improve protection of major geo-structures, trigger novel applications in civil engineering and foster the development of patentable sensors and data analysis methodology.Read moreRead less

This project aims to transform traditional civil structures into smart structures that can accurately identify current and future structural deterioration conditions and automatically notify the infrastructure management authority for timely maintenance. Civil structures deteriorate over their long life spans. Currently, we have no effective method to identify when deterioration has reached the point where maintenance is required. The project plans to develop innovative structural deterioration evaluation systems using output-only vibration data and versatile optimisation algorithms to enable long-term deterioration assessment and maintenance management even under demanding operating conditions. These could be used with both conventional data acquisition systems and modern monitoring systems with smart wireless sensors. Expected project outcomes will enhance structural safety and maintenance efficiency.Read moreRead less

Development of next generation prestressed concrete bridges using moving force identification. This project will enhance the safety of prestressed concrete bridges which constitute 70 per cent of Australian bridges and hence provide economic benefits. The procedure developed can evaluate the health status of these bridges and the prestressing force which was hitherto difficult to determine, even though it controls bridge load carrying capacity.

This project aims to systematically and thoroughly investigate the progressive collapse mechanisms and resistance capacity of concrete flat plate structures. They represent one of the most common construction systems used worldwide in modern days, yet their progressive collapse mechanisms require attention and limited collapse prevention design guidelines are available. The outcomes are expected to broaden and deepen the existing theoretical framework and knowledge base, prevent injury and loss of life in both new and existing buildings. This is expected ultimately to contribute to the establishment of a set of collapse-resistant design guidelines for further development of relevant Australian and international standards.Read moreRead less

This project aims to develop a high-performance tool for the dynamic safety assessment of softening structures. The assessment of structures that exhibit softening, either at constitutive level or structural level, is essential for design and rehabilitation purposes, especially when the inevitable uncertainties in the system parameters need to be accounted for. This project aims to develop an advanced and unified framework that can model both stochastic and nonstochastic processes for these purposes. An advanced mixed finite element model underpins this framework, and both formulation and solution algorithms are based on mathematical programming formalism. The developed computational tool would be able to perform pure stochastic, pure nonstochastic, hybrid uncertain analyses and dynamic reliability assessment of structures.Read moreRead less
