AGM & 50th Rankine Lecture: Stiffness at small strain – research and practice

The rapid development of computing power and of numerical modelling software over the past forty years has made sophisticated analysis of geotechnical problems accessible to most practising 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

From a 20kg Sample to a 100 million tonne land form: the art of tailings engineering

Few, if any, engineers start their professional careers with the intention of specializing in tailings engineering. In fact, few, if any, will have heard the word tailings mentioned during their university careers. And yet tailings storage facilities can be some of the most hazardous structures we build, using difficult materials in harsh terrain and climatic …more

Rock Mass Characterisation

The presentation deals with the integration of site geology with engineering requirements. Methods of rock mass characterization can now be tested with the aid of numerical analyses, and the suitability of the predictions they lead to can be tested with site instrumentation. Rock mass classification systems (such as RMR and Q) played an important role …more

Diaphragm Walls – Design and Construction

The presentation will initially review the concept, objectives and construction method of diaphragm walls. This will be followed by an interesting case study of a quay project whose concepts can be applied to projects of similar nature in Western Australian ports. Also, the concept of curved diaphragm walls without anchors will be introduced and a …more

Geotechnical Aspects of the Port Geographe development

Port Geographe is a residential canal development and marina located a few kilometres east of Busselton in Western Australia. Much of the development is located over dune sand and estuarine deposits. Extensive use has been made of surcharge preloading as a foundation improvement technique to treat the organic silt that underlies much of the site. …more

Urban Stormwater and Groundwater Management for Water Sensitive Urban Design Outcomes

The water sensitive approach to stormwater management aims to maintain the pre- development hydrologic regime. The Department of Water is promoting the design of stormwater infrastructure that addresses both quantity and quality management during frequent, low intensity rainfall events. Traditional design of stormwater infrastructure focused solely on quantity management and ‘disposal’ to provide flood protection …more

The Magic of Sands

David Muir Wood will reprise and update his Bjerrum lecture, presented recently in Oslo. The lecture begins with a description of an investigation performed at the WAC Bennett Dam, British Columbia, following the appearance of sinkholes at the dam crest. Investigations showed that there had apparently been movement of fine material out of the core …more

Lessons Learnt from Numerical Analyses of Geotechnical Problems

This presentation will be in two parts with Dr Mostafa Ismail leading the main presentation with a closing presentation by Sergei Terzaghi on specific numerical modelling for tunnels including a brief commentary on soil-structure interaction effects. Complexity of soil structure interaction problems is increasing due to continuing demand on existing infrastructures, including tunnelling, underpinning activities, …more

Pit Slope Design for Clermont Coal Mine, Central Queensland

Rio Tinto Coal Australia began mining operations at its Clermont Coal Mine in the first half of this year but coal will not be uncovered until 2010 making this a mammoth box-cut in the first two years of the mine’s operation. Since discovery of coal in the Wolfang Basin in 1979, the Clermont Project has …more

Estimating the Mechanical Properties of Rock Masses: Reflections on a career in Rock Mechanics

As a civil engineering student at the University of Melbourne in the late 1950s, the speaker naturally gravitated towards a specialisation in geomechanics (although the term wasn’t in use then), largely because of the influence of an inspiring undergraduate teacher and subsequent post- graduate supervisor, Professor Hugh Trollope. Partly as a result of having been …more

The Basic Theories of Soil Mechanics

Soil mechanics is an applied science; it deals with the mechanical behaviour of wet particulate materials and construction on and in them. There are fundamental theories of soil mechanics which come from other basic branches of mechanics. There are also theories which have been developed specifically for particulate materials. Some theories are for material behaviour …more
