Landslides, Risk Concepts and Case Studies

About the Presentation The presentation includes an overview of landslide types, mechanisms and discusses the role of preparatory factors and triggering causes in landslide occurrence. A brief history of Landslide Risk Management (LRM) in Australia is provided as background to a discussion of the Australian Geomechanics Society’s (AGS) 2000 and 2007 LRM Guidelines. A discussion …more

Measuring the pressure induced by bench blasting and deciphering explosive performance through rockmass response analysis

Abstract Rockmass response analysis in blasting is an important element for determining the performance of a blast along with its other outcomes. Near-field monitoring for rockmass response analysis is vital for determining the behaviour of a blast. However, due to costly and cumbersome methods involved in such measurements the subject has received scant attention so …more

Quantifying quantitative rock fall risk – How many rocks? How far?

Abstract AGS Landslide Risk Management Guidelines require that quantitative risk assessment be undertaken where there is a risk to life. When it comes to rock fall risk, a meaningful quantitative risk assessment often requires quantification of both boulder generation rates and travel distances. Three case studies are discussed each presenting methods of quantifying risk with …more

Reliability-Based Geotechnical Design:
From Theory to Practice

Abstract Geotechnical design codes are increasingly migrating towards reliability-based design concepts. What this means is that geotechnical designs are starting to be specifically targeted at a failure probability that is societally acceptable and that depends on both the severity of failure consequences and the level of understanding of the site and prediction model. For example, …more

2014 Terzaghi Lecture: Energy Geotechnology:
Enabling New Insights into Soil Behaviour

Abstract Energy is critical to life, and the coming decades will see worldwide population growth and associated economic development that will result in a pronounced increase in energy demand. Historically, geotechnical engineering has been crucial to projects that have sustained societal transformations. Once again, geotechnical engineering has a central role to play in the evolving …more

The Performance Characteristics of Granular Base using a Laboratory Wheel Tracking Device

Abstract A new wheel-tracking machine has been developed to improve the characterisation of granular materials used in pavement construction. It was designed and manufactured in Australia within the framework of current European standard specifications developed for asphalt materials. The laboratory performance data collected to date indicates that the approach appears suitable to assess the rut …more

Prediction of the excavation damaged zone in Callovo-Oxfordian claystone using a coupled second gradient model

Abstract The solution currently studied in France for long-term management of radioactive waste is the repository in deep argillaceous geological media with low permeability. The drilling of underground galleries in these clayey rocks induces damage propagation in the surrounding medium. This excavation process creates a damaged zone, in which the material properties are modified. The …more

E.H. Davis Memorial Lecture – Newcastle

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

Retaining Structures for Grade Separations

Abstract Over the next eight years, the State Government will deliver a coordinated program to remove 50 of the worst level crossings in Melbourne, improving safety, reducing congestion and enabling more frequent train services. Solutions which involve lowering of road or rail below ground level typically require carefully engineered retaining structures to minimise impacts on …more

A systems approach to verifying driven pile foundations

Abstract Over the past 30 years, dynamic pile testing (PDA) has become a generally accepted technique for verification of driven pile capacities in Australia. In the vast majority of projects, the technique is specified as a quick, inexpensive and generally reliable method for proof load testing for contractual verification. That being said, the implementation of …more
