Near-surface seismic: More than a problem of scale

Over the last 30 years, various seismic techniques have been successfully used to unravel some of the most intriguing and challenging near-surface problems faced by geologists, hydrologists, and engineers. In general, geophysicists define the nearsurface as the upper few hundred meters of the Earth’s surface. With the unique behavior and wavefield characteristics commonly observed on …more

Reinforced Soil Structures and the development of BS8006:1-2010

Geosynthetic materials offer the designer solutions for a wide range of soil stabilisation and ground improvement treatments in infrastructure projects, including hard faced walls, wrap-around faced green slopes, basal reinforcement and load distribution platforms. Our speaker, Stephen Corbet, will give an insight into the use of geosynthetic materials for soil reinforcement, and the development of …more

Geotechnical Practitioner of the Year 2010 and Civil Engineer of the Year 2011

Andrew is the current AGS Geotechnical Practitioner of the Year and Sir John Holland Civil Engineer of the Year. These are both prestigious awards within Australian engineering. The Civil Engineer of the Year award is presented annually by the Civil College of Engineers Australia to an eminent Civil Engineer considered to have made a major …more

Soil and Rock Logging – AS1726 Geotechnical Site Investigations

The course aims to educate geotechnical, environmental engineers, geologists and geotechnicians who find themselves logging and/or interpreting soil and rock logs in accordance with AS 1726 – Geotechnical Site Investigations. The content assumed that the participants already have a basic understanding of soil and rock logging. The course is particularly relevant to professionals starting their …more

Evaluation of Soil Liquification and Post-Earthquake Deformation using CPT

The presentation will provide a brief background on soil liquefaction and describe how the Cone Penetration Test (CPT) can be used to evaluate the potential for liquefaction as well as estimate post-earthquake deformations. Example case histories will be used to illustrate the methodology. The presentation will compare and discuss recent CPT-based methods.

51st Rankine Lecture – Geotechnical Stability Analysis

Historically, geotechnical stability analysis has been performed by a variety of approximate methods that are based on the notion of limit equilibrium. These techniques have the major disadvantage of the need to presuppose an appropriate failure mechanism. This can lead to inaccurate predictions of the true failure load, especially for cases involving layered materials, complex …more

Refinement of the Conceptual Ground Model for Melbourne Metro

Members and visitors are invited to a presentation on the ongoing refinement of the conceptual ground model for the proposed Melbourne Metro rail tunnels. Anthony Bennett, from the Public Transport Victoria’s Technical Adviser team, will set the context of the project, outlining the proposed new rail link beneath North Melbourne, the CBD, and St Kilda …more

“From Drought to Deluge” Case studies & Improving Slab Performance

“Recent changes to AS2870 and why” — Dominic Lopes, USL Group “Poor drainage, plumbing and other causes of house damage” — Paul Trentini, Storm Plastics “Slab movement cases studies – Trees, droughts, floods” — Dominic Lopes “A cost‐effective suspended slab for any site condition — Jim Prior, Polyvoid

Groundwater Issues Related to Tunnelling

Dr Harry Asche will illustrate the importance of hydrogeology in tunnel planning, design and construction. He will also discuss the fundamentals of hydrogeology; the tools used by hydrogeologists to define and identify the critical parameters; how to make sense of the data; and “tips for tunnellers”. Mike Dudding will talk about groundwater inflow measurements, during …more

Geomechanics & Engineering – “Pavements on Expansive Soils”

At the invitation from Don Cameron and the Footings Group SA, Professor Robert Lytton has agreed to conduct a lecture tour around Eastern Australia. The Housing Engineering, Design & Research Association, is organizing this tour with the help of the Adelaide, Brisbane, Newcastle, Sydney and Melbourne chapters of the Australian Geomechanics Society, FFS Queensland, FFS …more

Geomechanics & Engineering

Through the efforts of the Engineers Australia SA Division Footings Group and Dr Don Cameron, we present a lecture series by Professor Robert Lytton. This tour has been organised by the Housing Engineering, Design & Research Association (HEDRA) in conjunction with the SA, Queensland, Newscastle, Sydney and Melbourne chapters of the Australian Geomechanics Society (AGS), …more

Bogong Power Development Project Geotechnics

The completion of the Bogong Power Development Project during 2009 in the alpine region of north east Victoria involved construction of 7.6 km of tunnels and shafts and an underground power station. The project cost was $240 M and provided 140 MW of power. This project saw the completion of the ‘missing link’ in the …more

Design of Columnar-Reinforced Foundations

The design of columnar-reinforced foundation usually involves two verifications, first, the bearing capacity and, second, the settlement that can be completed by the acceleration of consolidation settlement. The basis of suggested methodology consists in estimating, first, a minimum improvement area ratio (IAR) complying with the allowable bearing capacity of reinforced soil; then a maximum IAR …more

Geology and Geomorphology of Bacchus Marsh Region: Field Trip

The geology and geomorphology of the Bacchus Marsh region has been of interest to geologists since the 1860’s, with a wide range of rock types of various ages and depositional environments present. The extraction of natural resources has been an important industry in the area, with brown coal, basalt, sands and gravels worked from the …more

Probabilities of Failure and Factors of Safety in Geotechnical Engineering

There has been a rapid growth of interest in both academe and industry in the use of probabilistic methods in geotechnical engineering. In hindsight this is not too surprising, since soils and rocks are among the most variable of all engineering materials, and geotechnical engineers must often make do with materials they are dealt with …more
