55th Rankine Lecture:
Hazard, Risk and Reliability in Geotechnical Practice

“Doubt is an uncomfortable condition, but certainty is a ridiculous one” – Voltaire Abstract More and more, society requires to know the risk which people, property and the environment are exposed to. The role of the geotechnical engineering profession should increasingly be reducing exposure to threats, reducing risk and protecting people. The objective of the 55th Rankine …more

Abandoned Mine Subsidence Geomechanics

This is a joint presentation with AusIMM Hunter Region. Analysing the mechanisms governing subsidence over old abandoned mines About Ebrahim Fathi Ebrahim Fathi is a Geotechnical Engineer with over nine years of experience in rock mechanics, and the design and stability analysis of surface and underground excavations. He served as a tunnel engineer for the …more

Be careful with reactive clays – some case histories

Abstract Reactive clays underlie much of Sydney and the surrounding areas. Guidance for design to cope with reactive soil movements is presented in AS2870 ‘Residential Slabs and Footings’. The principles for investigation and design are well established and should be known to practicing geotechnical engineers and engineering geologists in the Sydney area. Nonetheless, problems still …more

Disruptive technologies and a view of the future for geotechnical practice

About the Presentation James’ presentation will provide a view on the role that emerging and established technologies can play in shaping the future of geotechnical practice – both in terms of ground characterisation and construction activity. James will discuss technologies that sit at various “technology readiness levels” – some having benefits to projects of today …more

Ground Treatment: Taming the Angryman, and other grouting challenges

Presented by AGS Victoria together with ATS. This is the third consecutive joint technical session between the ATS and the AGS under the heading of “Ground Treatment”. This presentation will focus on the many varied applications for what we loosely term “grouting” but more specifically injection or pressure grouting for groundwater control and ground strengthening in …more

E.H. Davis Memorial Lecture – Victoria

Introduction This biennial lecture commemorates the work in geomechanics by Professor Edward Hughesdon Davis. Professor Davis was one of the pioneers of geomechanics in Australia. He perceived that progress and understanding of the theoretical basis of geomechanics would only come if consistent, sound, but simple models of soil behaviour were used. The two topics that …more

Key learnings from conducting In Situ Testing

Please click here for details of the Field Demonstration entitled “Cone Penetration Testing (CPT) and Seismic Dilatometer Testing (SDMT) Field Demonstration”, presented by Nick Ramsey, which will be held earlier in the day from 1.30pm at Tarver Street, Port Melbourne. Abstract Soil behavior is complex and thus requires quantification by a reasonably good number of …more

Pitfalls in the Interpretation of Water Content Based Soil Water Characteristic Curve for Unsaturated Soils

Abstract The soil water characteristic curve (SWCC) is one of the most fundamental relationships in the mechanics of unsaturated soils. It enters calculations relating to deformation, shear strength, effective stress, fluid flow, water retention, drainage, water balance, and appears explicitly in the constitutive formulations of pore-air and pore-water, satisfying pore-phase volume change compatibility for a …more

Energy and Environmental Geomechanics

Abstract In the last few years geotechnical engineering has expanded its domain into the field of Energy Geotechnics. This has led to the study of the behaviour of soils and rocks under complex and extreme conditions involving mechanical, hydraulic, thermal, and geochemical coupled actions. This branch of geotechnical engineering will play a fundamental role in …more
