Unsaturated soil mechanics and the effective stress in design practice: with application to retaining wall design and CPT interpretation

Abstract Unsaturated soils are widely encountered and need to be dealt with in many engineering problems, for example foundations, fills, embankments and slopes. In many cases true predictions of performance and assessments of safety cannot be made without use of unsaturated soil mechanics. In this presentation it will be demonstrated how practitioners can apply unsaturated …more

Mechanics of Unsaturated Soils

Abstract The effective stress principle is one of most fundamental contributions in the field of soil mechanics. It converts a multi–phase, multi–stress state porous medium to a mechanically equivalent, single-phase, single-stress state continuum, thus allowing the application of the principles of continuum solid mechanics to fluid-filled deformable porous media. Without the advent of the effective …more

AGS SA-NT Seminar 2016

Design considerations for cuttings, revetments and retaining structures for unsaturated clay The SA/NT Chapter of the Australian Geomechanics Society is pleased to announce our one day seminar for 2016. This forms part of a continuing series of technical events organised by the Chapter and will focus on design for unsaturated clay. Who should attend? Geotechnical …more

El Viar Dams In Southern Spain:
Embracing Expansive Clay

Dam Construction Using Expansive Clay,<br>Case Study of two dams built in Southern Spain in 2007-2008 Abstract The use of expansive clay in road construction and dry embankments is well established thanks to traditional soil stabilisation methods. However there is relatively little experience in the use of expansive clay for the construction of large earth dams …more

Risk Management for Onkaparinga Coastal Cliffs

Abstract Onkaparinga Council is responsible for managing approximately 30 km of coastline, comprising a wide variety of coastal land forms and geologies including spectacular cliffs and stunning beaches. However, along with its outstanding natural beauty, this coastal strip is also subject to significant and ongoing erosion and slope instability as a result of the dynamic …more

SA-NT AGM, followed by the 55th Rankine Lecture:
Hazard, Risk and Reliability in Geotechnical Practice

The lecture will immediately follow after the SA-NT Chapter Annual General Meeting. “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 …more

AS 1726 : 2016 Seminar – Adelaide

SYNOPSIS The most recent edition of Australian Standard 1726 – Geotechnical Site Investigations was released in 1993. In 2011 the AGS surveyed its members and stakeholders to consider possible revision of this Standard. This survey included a total of 25 questions, with 17 pertaining to the technical content of a possible revised Standard. Subsequently AGS …more

Engineering for Adelaide Earthquakes

About the Presentation This lecture explores the nature of earthquake ground motion and its effects on buildings. It gives an overview of the seismic hazard in Adelaide and discusses the likelihood of various levels of ground motion. Finally it discusses what can be done to improve building response and whether we, as residents, should be …more

2014 AGS Practitioner Award Distinguished Lecture in Adelaide

ESCAPING THE GOLDEN CAGE*

Learning to Practise the Art of Observational Geotechnical Engineering

Abstract The observational method is a respected and much-quoted pillar of geotechnical practice, but it appears in many guises and its application is not always clearly understood or appreciated. At its heart is the engineer’s dilemma of getting something to work safely and efficiently in the face of uncertainties. Observational geotechnical engineering is the art …more

E.H. Davis Memorial Lecture – SA-NT

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
