The essential requirements for the design of foundations for the world’s tallest buildings, from a geotechnical perspective are presented. The basic types of foundation, special in-situ testing, and load testing techniques commonly used, and several key principles to remember including the need for close structural engineering and geotechnical engineer cooperation are discussed.

The first part of the seminar will deal with why we get earthquakes in South Australia, probabilistic seismic hazard analysis and the earthquake hazard in the state. Later speakers will deal with the revised earthquake loading code and various aspects of earthquake engineering including the performance of masonry structures, site amplification and seismic design, pile …more
Most of you will have built a retaining wall in a stiff clay. You excavate the clay, often to a steep slope, and it stays there while you build the wall and backfill. During this time you’re thinkinghellip; “Why am I building a wall to retain this clay?” You comfort yourself with the thought that, …more
The essential concepts underlying the “total engineering geology approach” will be described e.g. the use of staged investigations, the adoption of a rigorous scientific approach, the role of geo-mapping, the establishment of reference conditions, the development of different types of geo-models, the application of the observational method etc. How the approach can be used to …more
Over the past decade, a number of developments have been made in buried pipe design, based on laboratory testing and computer analysis. These rely on improved understanding of soil-pipe interaction, and new information regarding the strength limits of metal, fibre reinforced cement, thermoplastic and composite pipes. Various aspects of buried pipe and culvert design are …more
John’s talk will cover a range of experiences that he would have preferred not to have had in a 40 year career in geotechnical work. However, there are lessons to be learnt so that younger engineers will make their own mistakes and not repeat these ones. The talk will initially cover two dam failures in …more
The rapid development of computing power and of numerical modeling software over the past forty years has made sophisticated analysis of geotechnical problems accessible to most practicing 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
The aim of the evening is to give younger members of the profession the opportunity to present to their peers on a technical theme. Presenters gain valuable presentation experience in a relaxed atmosphere while enhancing their professional development and sharing knowledge to the geotechnical community.
You receive a Brief for a project where the client states “the consultant shall address the effect of climate change predictions on the project”. How will you deal with this challenge? Dr Peter Mitchell will outline an approach to this question by describing the predictions of climate change in Sydney, Melbourne and Adelaide, and the …more
2009 E.H. Davis Memorial Lecture: Recent Advances in the Application of Vertical Drains and Vacuum Preloading in Soft Soil Stabilization
Much of the world’s essential infrastructure is built along congested coastal belts composed of highly compressible and weak soils up to significant depths. Alluvial and marine soft clay deposits have very low bearing capacity and excessive settlement characteristics, with direct design and maintenance implications on tall structures, large commercial buildings, as well as port and …more
Presentation details The production of high quality, engineering related documentaries has increased greatly over the last 5 to 10 years. You may have seen some of these on free to air television, while many others are only available on pay television or DVD and hence may be unfamiliar to you. Through the agency of Australian …more
The revised Standard “Piling — design and installation”, referred to locally as the Australian piling code, was introduced in late 2009. The changes from the 1978 Standard to the 1995 Standard were major, with the introduction of limit state analysis among other significant changes. AS 2159-2009 has continued that trend, with major changes throughout the …more
Allan McConnell will discuss in situ geotechnical testing. The underlying theme will be “reducing geotechnical uncertainty”. The presentation will be a “warts and all” dialogue, covering: What is reasonably available to a geo-engineer in Australia. What is it good for – and strengths and weaknesses. How good is it really? Why does it help to …more
This presentation will cover a range of pavement types – concrete, asphalt and interlocking concrete blocks. The particular differences between road and aircraft / container pavements will be highlighted. The background to the design methods will be presented along with a discussion of examples.
