The Re-Use of Sediment Drained from the Patawalonga

Between the middle of 1995 and the middle of 1996, approximately 300 000 m3 of sediment was dredged from the Patawalonga Basin. The sediment was deposited in ponds along Tapleys Hill Road and the water drained from it. In July 1996 accelerated drainage measures were instituted which allowed the material to be removed from the More Information…

Annual visitors night: India – Roads and Life

Did you ever wonder why the Taj Mahal has lasted as long as it has? Did you ever wonder how they build roads in India? In this seminar Bob regaled us with pictures and words of his recent trip to the subcontinent where he went to exchange knowledge on the intricacies of road building, and More Information…

Construction of the Blanchetown Bridge

Construction of the new bridge at Blanchetown is nearly complete. The new bridge was incrementally launched and its deck is a post tensioned concrete box girder 407m long. Some difficult ground conditions and the close proximity of the existing bridge posed problems for both design and construction. Prior to construction, predictions were made of the More Information…

Collapsing Soils

Collapsing soil is defined in AS2870 as a weakly cemented soil subject to large settlements under load as a result of degradation by water on the cementing action. These soils are frequently encountered in South Australia and present challenges for geotechnical engineers and footing designers. Dr Mitchell described some experiences with collapsing soils, presented several More Information…

Cobblers Creek Retention Dam Project

The Cobbler Creek retention dam in the City of Salisbury was constructed in 1997. Exposures seen during excavation for the dam and spillway foundations provided interesting insights into the geological formations in the foothills of the Mount Lofty Ranges. These formations, including the Quaternary sediments and folding and faulting of the underlying rocks, were discussed More Information…

Southern Expressway Project

Stage 1 of the Southern Expressway project between Darlington and Reynella has been one of the most significant road projects in recent times both from environmental and geotechnical aspects. This seminar covered many of these aspects and included a detailed discussion of a number of slope stability “challenges” that were encountered.

Annual Half-Day Seminar – Recent Developments in Pavement Technology*

Speakers include: Richard Cavagnaro, Don Cameron, Bob Andrews, Doug McInnes, Ted Booth, Chris Mathias, Kevin Mills, Craig Gilbert Increased Legal Axle Loads Resilient Modulus Variations in Clay Subgrades Crushed Rocks Related to Pavement Performance Haul Road Design Recent Advances in Sealing Technology New Applications for the Falling Weight Deflectometer Recent Experience with Local Pavements

Mt Barker Road Project Visit

This meeting involved a visit to the South Eastern Freeway project and a talk by Andrew Campbell from Maunsell who is involved with the geotechnical design on the project. The visit and the talk covered all aspects of the project including the design and stabilisation of the rock slopes between the Tollgate and Crafers, the More Information…

Modelling of Offshore Foundations

The lecture focussed on recent results of physical and numerical modelling of a range of foundation systems in uncemented calcareous sediments typical of Australia’s offshore hydrocarbon fields. Foundation types included skirted foundations, suction-emplaced caissons, and drag anchors. In each case, simplified models of behaviour were described, and the results compared with those from more sophisticated More Information…

Inaugural Young Geotechnical Engineers Night and Annual General Meeting

A total of 5 young geotechnical engineering graduates and students individually gave a 10 minute presentation on a range of interesting projects. The winner of the Inaugural Geotechnical Engineer’s Night was Brendan Scott, Final Year Civil Engineering Student, University of Adelaide.

Engineering Characteristics of Interesting South Australian Soils – Woomera, St Kilda And Glanville Formations (Joint Meeting with the S.A. Footings Group)

Woomera: The soil conditions of the Woomera area are a reminder that every project requires a site specific geotechnical investigation. Don Richardson discussed interesting aspects of ground engineering in the Woomera area, such as gilgai formations, gypsum, soil suction and ground movements. St Kilda and Glanville Formations (Geology): Tony Belpirio discussed the geological characteristics of More Information…

1995 E. H. Davis Memorial Lecture Video Presentation

Due to a late cancellation of a scheduled speaker, it was decided to show a video of the 1995 E. H. Davis Memorial Lecture Presentation by the Late Prof. John Booker. Many of the audience had not seen the lecture previously and appreciated the opportunity of seeing John’s presentation.

The G-Pile Foundation System

The G-Pile System of pile construction was developed in South-East Asia where it has been widely used. It was introduced into Australia in 1998 by the Australasian Piling Company. The G-Pile system is a hydraulic jacking pile installation that uses a patented grip (hence the name G-Pile for grip pile) to inject the pile into More Information…

Annual Half-Day Seminar – Ground Engineering Risk

Speakers include: Dr. Peter Redman, Don Richardson, Judy Carr, Bruce Bate, Luigi Rossi, John Woodside, Peter Fisher, Dr. Mark Jaksa, Richard Cavagnaro, Richard Herraman The aims of the half-day seminar were: To share how different stakeholders perceive and manage ground engineering risk; To understand better the constraints under which different stakeholders operate; To identify collective More Information…

Southern Expressway Stage I – Pavement Design and Construction

Stage 1 of the Southern Expressway project between Darlington and Reynella has been one of the most significant road projects in recent times from environmental, geotechnical and pavement design aspects. Over the past year there have been very interesting presentations on the former two of these issues. In this month’s talk Rob Bremert presented the More Information…
