Culverts and Sewers – Buried but not forgotten

While largely out of sight and neglected for decades, the deteriorated state of our buried pipe infrastructure is now attracting considerable attention. An overview of a number of recent studies is presented, featuring both experimental and computational work to explore soil-pipe interaction and the performance of new, deteriorated, and repaired pipe systems. The presentation starts More Information…

Stiffness at Small Strain – Research and Practice

The rapid development of computing power and of numerical modelling software over the past forty years has made sophisticated analysis of geotechnical problems accessible to most practising engineers. Typically computer packages now offer a wide range of constitutive models, which the design engineer needs to choose between, and then obtain parameters for. For those structures More Information…

Concepts & Parameters Related to Ground Improvement Illustrated by Case Histories

The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee on Ground Improvement, has proposed a classification system of ground improvement techniques according to the general nature of the soil, (frictional or cohesive) and the inclusion or not of added material (http://www.bbri.be/go/tc17). This classification system has been detailed in the state of the More Information…

The NSW Research Award: Advances in Geotechnical Engineering Research

Ali Ghandeharioon Analytical and Numerical Studying of Disturbance and Pore Pressure in Soft Cohesive Soils Associated with the Installation of Mandrel-driven Prefabricated Vertical Drains This research investigates the installation of mandrel-driven PVDs and the associated disturbance in cohesive soils using a novel elliptical cavity expansion theory validated by laboratory experiments and numerical modelling. The pattern More Information…

Recent Advances in the Application of Vertical Drains and Vacuum Preloading in Soft Soil Stabilisation

Pre-construction consolidation of soft formation soils by applying a surcharge load alone often takes a long time, thereby impacting the construction schedule. Moreover, attributed to the low permeability and high thickness of low-lying clay deposits, the required surcharge load to achieve more than 90% degree of consolidation can be excessively high over a prolonged period.

Slurry Wall Construction Current Technology and Case Studies

Geo-Solutions Inc is a world leader in geotechnical construction, specialising in slurry walls. Geo-Solutions and Menard Bachy as a partnership have completed numerous successful Australian projects including remediation of the former BHP Site in Mayfield. We are fortunate to have Chris in Newcastle in March to deliver a presentation outlining the latest slurry wall technologies More Information…
