Foundation remediation using resin injection. The aim of this research project is to explore the application of injected expanded polyurethane resins as a new option for the re-levelling and stabilisation of deflected foundations on reactive clay soils. It will identify the physical and behavioural characteristics of resin-injected reactive clay foundations, in the context of both shallow and deep injection, and will identify any limitations to the applicability of the approach. Based on detaile ....Foundation remediation using resin injection. The aim of this research project is to explore the application of injected expanded polyurethane resins as a new option for the re-levelling and stabilisation of deflected foundations on reactive clay soils. It will identify the physical and behavioural characteristics of resin-injected reactive clay foundations, in the context of both shallow and deep injection, and will identify any limitations to the applicability of the approach. Based on detailed laboratory and field testing, and advanced numerical modelling, the outcome will be the ability to confidently assess various foundation remediation strategies in reactive clay soils, and provide much needed design guidance to the geotechnical profession and building industry.Read moreRead less
Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can conside ....Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can considerably benefit from the findings of this project including safer structures, significant reduction in the future maintenance costs and enhancing the performance of bridges, buildings, roads, railways and dams with less cracks and differential settlement.Read moreRead less
Retrofitting unreinforced masonry walls with fibre reinforced polymer strips. An efficient technique for increasing the safety of existing masonry structures under earthquake (and other) loading will be developed. This is essential to the safe continued use of existing infrastructure (avoid replacement = economic benefit). This new technique addresses many shortcomings in existing alternatives (increased performance, reduced cost). This research is particularly important in Australia where unrei ....Retrofitting unreinforced masonry walls with fibre reinforced polymer strips. An efficient technique for increasing the safety of existing masonry structures under earthquake (and other) loading will be developed. This is essential to the safe continued use of existing infrastructure (avoid replacement = economic benefit). This new technique addresses many shortcomings in existing alternatives (increased performance, reduced cost). This research is particularly important in Australia where unreinforced masonry accounts for most domestic construction, much light commercial infrastructure, as well as many heritage and post-disaster buildings. It also reinforces Australia's high international standing in developing innovative retrofitting alternatives using advanced materials in this rapidly developing area. Read moreRead less
