Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. ....Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. The main aim of this project is to achieve technological advancement in sustainable and cost effective PVD-vacuum systems by minimising the time to achieve the desired degree of consolidation, thereby controlling post construction settlement and lateral movement. Extensive laboratory and field studies supported by numerical modelling aim to result in new industry guides and standards.Read moreRead less

Summary
A national facility for in situ testing of soft soils. A mobile in situ testing laboratory will permit the investigation of devices for measuring geotechnical conditions on soft and swampy sites which are often being encountered on key infrastructure projects. The new facility will improve the modelling and testing of soft soils and ensure the safe and economic development of Australian infrastructure.
Fundamental study of fracture-controlled compensation grouting for ground movement. This project aims to investigate the fundamentals of fracture-controlled compensation grouting in various types of soil, so as to optimise the compensation efficiency and to minimise the risk of collapse of nearby structures. This will result in the minimisation of ground movements induced by underground excavations, which pose a major threat to existing infrastructure and communities worldwide. Small-scale labor ....Fundamental study of fracture-controlled compensation grouting for ground movement.

This will result in the minimisation of ground movements induced by underground excavations, which pose a major threat to existing infrastructure and communities worldwide. Small-scale laboratory experiments, centrifuge tests and numerical analyses will be conducted to develop an effective and economical grouting method that will provide a valuable design tool for engineers.Read moreRead less

Load-displacement and consolidation behaviour of soft soils stabilised by stone columns for transport infrastructure. The project outcomes will guarantee better understanding of the benefits of stone columns for stabilising soft soil foundations through numerical and experimental processes. The enhanced load-carrying capacity and mitigation of excessive soil movements will contribute to sustainable development of transport infrastructure.

Cyclic behaviour of unstable soils stabilised by lignosulfonate with special reference to rapid transport infrastructure. The project will pioneer the use of the paper industry by-product, lignosulphonate, to stabilise unstable soils in rural and regional Australia. The prevention of unacceptable erosion, settlement and mass movement of these soils will enable efficient operation of high speed rail and busy highways that are vital for agriculture and mineral industries.

The effects of cyclic loading on partially saturated soils. This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numeric ....The effects of cyclic loading on partially saturated soils.

Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numerical model that can predict the effects of cyclic loads, and provide updated engineering guidance to ensure the integrity of infrastructure dependent on partially-saturated soils. Improved predictions of the processes involved resulting from this project will have significant economic benefits, as well as ensuring the safety and security of infrastructure and reduced maintenance costs.Read moreRead less
