2011 Meetings

Drilled Shaft Instrumentation for O-cell Tests

In this talk the general requirements for O-cell instrumentation will be presented, including the differences in instrumentation required for O-cell bi-directional static load tests to conventional load tests, purpose and numbers of various embedded instruments, parameters that need to be measured, instrumentation for additional geotechnical parameters, calculation of plate movements – single level and multi …more

2009 Rankine Lecture: Geohazards and Large Geographically Distributed Systems

Geotechnical engineers play a critical role in managing the performance of large geographically distributed systems that are affected by geohazards such as earthquakes, floods, hurricanes, and landslides. Systems, such as water supplies, levees, and gas and liquid fuel supply networks, may cover thousands of km2 and be subject to many different ground response and geotechnical …more

AGS Young Geotechnical Professional’s Night

The Young Geotechnical Professionals’ Night is an opportunity to see four selected presentations by young geotechnical professionals discussing interesting and challenging aspects of their work. After the presentations, you will have a chance to catch up with friends and the presenters over drinks and finger food, and see additional posters prepared by YGP’s. The following …more

Salinity in Western Sydney

Dryland Salinity is an issue that has become increasingly apparent with urban expansion across Australia, affecting buildings, infrastructure and the environment. This presentation covers an overview of the occurrence, salinity processes, engineering issues, investigation methodologies, assessment of impacts, design related management planning / reporting, monitoring and adoption of salinity techniques within DA certification requirements. The …more

Working Platform Assessments for Tracked Plant

Every year piling rigs fall over or are subject to near misses due to inadequately prepared or maintained site surfaces – often such incidents involve potential fatalities or serious injury to operatives and extensive damage to equipment. Modern piling equipment is becoming increasingly heavy, often with higher centres of gravity, to cater for the demand …more

Building 3D models of rock strength using geophysical logs

Through a series of projects funded by the Australian Coal Industry Research Association (ACARP), we have developed a rock mass rating scheme for coal measure rocks which draws upon the compositional data contained within the geophysical logs as well as the sonic data. The scheme is known as the Geophysical Strata Rating (GSR) and our …more

Geotechnical Challenges and Lessons

This talk will present an overview of many of the significant projects on which Andrew has worked. It will include discussion of the salient features and present the “take-away” lessons from a number of geotechnical projects; it will include discussion of the background to the development of the Landslide Risk Management framework for Australia, and …more

2011 Symposium – Coastal and Marine Geotechnics: Foundations for Trade

The need to design safe foundations for offshore and near shore structures has generated greater interest in coastal and marine geotechnics, today an important element in geotechnical engineering. Achieving safe foundation design requires continuing evolution and discussion of design practices and construction techniques by geotechnical and marine professionals. The Symposium will present state-of-the-art practices, innovative …more

Rankine Lecture – Geotechnical Stability Analysis

Presentation details Historically, geotechnical stability analysis has been performed by a variety of approximate methods that are based on the notion of limit equilibrium. Although they appeal to engineering intuition, these techniques have a number of major disadvantages, not the least of which is the need to presuppose an appropriate failure mechanism in advance. This …more

The Lessons From The Yallourn Enquiry

Presentation details The northern batter of the Yallourn mine collapsed suddenly on the 14th November 2007. The collapse had dramatic consequences with loss of 20% of Victoria’s power generation capacity and a cost to the mine measured in hundreds of millions of dollars. Because this was a surprise to government and because of the consequences, …more
