Meeting

Annual Visitors Night

The AGS committee has organised our annual visitors event for members and guests of the SA Chapter of the Australian Geomechanics Society to meet and be entertained in a social atmosphere. The AGS committee has also invited members of the AusIMM committee to attend this social event to foster closer relations between the two professional More Information…

Screw Pile Anchors

Screwpiling has been used since the early 1990’s in Australia. Screwpiling is not new having been used in England in the 1830’s and in Indonesia by the Dutch in colonial days. Screwpiles can be used in piled foundations as an alternative to other piling systems. However, the strength of screwpiles is often limited by the More Information…

What Is Failure And Why Do Failures Occur?

Ground engineering is a risky business; there is much that can, and does, go wrong. Failures of construction in the ground can be more than just slips, excessive settlement or flooding. Sometimes failure of the ground is a requirement of the design. The talk will consider the nature of geotechnical failures in a wide sense. More Information…

Deep excavations in soft ground using temporary structural steelwork

In many city areas, ground anchors and soil nails cannot be used for deep excavation retention in soft ground due to construction constraints including adjacent structures. A solution often used I braced excavations involving temporary structural steelwork, serving multiple functions, like strutting, waling, lagging, traffic and construction decking. Based on Chris’s design and supervision experience More Information…

Terzaghi Lecture – Uncertain Geotechnical Truth and Cost-Effective High-Rise Foundation Design

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.

Seminar on seismology & earthquakes

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 Information…

Revetment Walls for Unsaturated Clay

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 Information…

The Application of the Total Engineering Geology Approach

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 Information…

Design of buried pipes and culverts

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 Information…

Failure and near Misses in a Geotechnical Career

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 Information…

Rankine Lecture: Stiffness at Small Strain – Research and Practice

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 Information…

Soils, Footing Designs and Climate Change

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 Information…

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 Information…
