One of the largest “design and construct” above ground bio-remediation projects implemented in Australia has been completed recently at the former Mile End rail-yards site, Adelaide. A total of 8,000m3 of diesel and oil impacted soil was successfully treated using the ENB process. This process involved the growth stimulation of naturally occurring aerobic micro-organisms and …more
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
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
Each year, the last meeting is devoted to a social event where members and others are encouraged to bring along their wives and partners for a fine and inexpensive meal. This year, Bill Stacy gave a facinating insight into early road building in South Australia.
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.
The 15 m wide by 9 m high tunnels of Melbourne’s City Link Project presented a series of geotechnical and hydrogeological problems during design and construction. The 3.6 km and 1.6 km long tunnels were, at times, driven beneath a major confined alluvial aquifer with minimal rock cover. Mr. Hutchison gave an overview of the …more
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
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 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
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
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
The site visit included a tour of the recent construction along the Glenelg to West Beach foreshore including the Glenelg foreshore development, the West Beach marina, Tapleys Hill Road Deviation and the Adelaide Airport runway extension.
Each year, the last meeting is devoted to a social event where members and others are encouraged to bring along their wives and partners for a fine and inexpensive meal. The evening includes a non-technical presentation.
Eurocode 7, on Geotechnical Design, is one of a suite of 9 European codes for the design of buildings and civil engineering structures. Work on Eurocode 7 started in the early 1980s, and it was published as a draft for development in 1995. A final version is due for publication in 2001. It is intended …more
Speakers include: Neil Schunke, Chris Hughes, Klayton Stivers, Julianne Martin, Nigel Brooks Five young geotechnical engineering graduates and students individually gave a 10 minute presentation on a range of interesting projects. Members of the Committee adjudicated that Klay Stivers, URS, Adelaide was the winner was presented with a certificate and a $250 cash prize.
Prof. Harry Poulos: Recent Developments in Piling and Ground Movement Around Piles Ray McMillan: 50 Years of Piling Peter Mitchell: Site Investigation and Assessment of Piling Options Paul Moritz: Piling Specifications: Good and Bad Slav Tchepak: Developments in Concrete Injected Piles Nicholas Morgan: Piling for the Pelican Point Project Michael Vadasz: The G-Pile System Prof. …more
Case Studies in Geotechnical Engineering (Joint Meeting with the S.A. Footings and Structural Groups)
Richard Herraman: Assessing the Performance of the Footings on the Commercial Road Railway Viaduct at Port Adelaide The loads on transport infrastructure are continually increasing. How can we determine whether the footings of old bridges will perform satisfactorily under proposed load increases? What is a cost to effectively upgrade the footings? We also know that footing …more
This presentation discussed a number of geotechnical projects in which the Pressure Injection Process has been used. These projects include railway and road stabilisation and contaminated ground remediation. According to the contractor, the range of uses for the process are limited only by the imagination. The presentation also presented some procedures that, although not yet …more
Adam Kilsby: Contaminated Soil – Take it or Leave it The viability of redeveloping ‘brown fields’ sites within South Australia can be significantly influenced by residual soil contamination associated with past land use. The viability is particularly relevant for residential developments on former commercial/industrial sites, where changing the land use to one more sensitive can …more
