The response of beams subjected to axial load and lateral soil movements. Beams (piles, soil nails, and pipelines) are not only subjected to axial (vertical, axial and longitudinal)loading, but often withstand simultaneous lateral loading, due to either explicit structural loads, or due to loads induced by movement of the soils in which they are founded. Bridge piles adjacent to an approach embankment are one example. This project will provide experimental evidence to assist with the estimation ....The response of beams subjected to axial load and lateral soil movements. Beams (piles, soil nails, and pipelines) are not only subjected to axial (vertical, axial and longitudinal)loading, but often withstand simultaneous lateral loading, due to either explicit structural loads, or due to loads induced by movement of the soils in which they are founded. Bridge piles adjacent to an approach embankment are one example. This project will provide experimental evidence to assist with the estimation of capacity, axial and shear resistance, the validation of unified solutions for beams subjected to simultaneous lateral soil movements and axial loads. Such experimental evidence and analytical solutions are not currently available. The evidence will also assist with solving a contradictory, existing design principle, which will lead to an economic and efficient design approach.Read moreRead less
Development of a new technique to improve very soft soils using geogrid wrapped stone columns. Many large Australian infrastructure projects will be developed in regions with inherently poor soil conditions. Port developments, for instance, are by their nature located in river estuaries which are characterised by deep deposits of soft alluvial soils. Many highway projects also traverse low-lying ground or coastal regions with soft soil conditions. This project will develop a novel technique to ....Development of a new technique to improve very soft soils using geogrid wrapped stone columns. Many large Australian infrastructure projects will be developed in regions with inherently poor soil conditions. Port developments, for instance, are by their nature located in river estuaries which are characterised by deep deposits of soft alluvial soils. Many highway projects also traverse low-lying ground or coastal regions with soft soil conditions. This project will develop a novel technique to improve the engineering characteristics of very soft soils (shear strength lower than 15 kPa) by using geogrid wrapped stone columns. The effectiveness of this technique will be investigated in both small scale laboratory tests and field trials.Read moreRead less

Summary
Innovative risk analysis, assessment, rehabilitation and strengthening of aging critical civil infrastructure. Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community.

Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community. Australia is not spared by the ramifications of its aging civil assets, and identification and rectification procedures that are often ad-hoc now represent a sizeable proportion of the GDP. This Research Network draws together the leading Australian research groups in engineering and applied mechanics in a coordinated program to address this most important cost to the community.Read moreRead less
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 para ....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.Read moreRead less
Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if ef ....Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if effective methods can be found to minimise such damage. This project proposes to study a novel technique, in which blends of hydrophobic polymer additives are used to increase the stability of geomaterials subjected to varying moisture levels and traffic loading.Read moreRead less
SCANEM : A Scanning and Inspection Method for Urban Pipeline Systems. Water and sewage utilities are crucial factors limiting economic growth and urban amenity. However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement.

However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement. Suitable strategies involving a structural audit and statistical analysis have been proposed by CSIRO and Tyco Water. However new geophysical inspection methods are now required to provide the key physical parameters relating to pipeline condition. Hopefully the EM inspection tool resulting from this project will provide the industrial partners with a unique capacity to satisfy a major global market.Read moreRead less

Australian Research Council has recognised water as a critical resource that must be protected from wastage. Along with water, the supply of gas to communities through extensive buried pipe networks is an essential service. As the pipe systems age, the pipe failures have increased. These failures lead to loss of valuable commodity and inconvenience and health hazard to public and workers. Effective asset management tools are urgently required in predicting and controlling pipe failures. A consortium of water and gas suppliers and a team of researchers from Monash University and CSIRO have joined forces to address this problem so that significant social and economic benefits to Australia can be realised.

However, with the large accessible reserves in shallower waters becoming exhausted, Australian oil and gas companies require new technologies to extend their capabilities. The research in this proposal addresses this concern, providing an extension of the operational depth range of mobile jack-up platforms from 120 to 200 m. This creates the opportunity to develop the significant number of Australia's smaller gas fields that are currently uneconomical to exploit. The proposed project will contribute to the future competitiveness of Australia's oil and gas industry and ensuring energy supply for the sustained growth of the Australian economy.Read moreRead less
