E.H. Davis Memorial Lecture 2012: Combined Loading of Offshore Foundations

Predicting the bearing capacity of a foundation under combined vertical (V), horizontal (H) and moment (M) loads is a fundamental soil mechanics problem. Traditional solutions utilise ad-hoc adjustment factors to reduce the pure vertical bearing capacity in order to account for inclination, eccentricity, foundation shape and soil strength gradients. These procedures have their roots in …more

Soil & Rock Logging Course – AS1726 Geotechnical Site Investigations

This one day course will aim to educate geotechnical engineers, geologists, geo‐technicians and other relevant professionals in logging and/or interpreting soil and rock logs in accordance with AS1726 – Geotechnical Site Investigations. This course is aimed at educating the profession and is particularly relevant to geotechnical and mining consultants, geotechnical contractors and laboratory geo‐technicians and …more

Sustainable Aggregates Information Seminar

The purpose of this short seminar is to present the outcomes of the Sustainable Aggregates SA development project undertaken by ARRB under a grant provided by Zero Waste SA, and equally supported by industry organisations Adelaide Resource Recovery and Resourceco. Through the development of a website the project has sought to provide industry in terms …more

Rankine Lecture: Performance Based Design In Geotechnical Engineering

Engineering design consists of a sequence of decisions which should satisfy the client’s objective performance requirements. This lecture will argue that an assessment of geotechnical performance must involve ground displacements, and that the traditional approach of specifying safety factors is potentially wasteful. In particular, the Limit State Design (LSD) approach adopted in the Eurocodes will …more

AS2870 – 2011, Residential Slabs and Footings

What should the geotechnical profession know about the changes in the Code? The Code gives references to parties their functions and responsibilities to using the code. An example is the Classifier and Qualified Engineer. Reference is made to role of Engineering Geologists and Geotechnical Engineers. To understand the responsibilities of the qualified engineers using the …more

Quality Assurance of ground improvement using down-hole video techniques

Verification of ground improvement is a topic of on-going debate. The tried and tested methods are limited in certain conditions and the geotechnical fraternity is always exploring new avenues for verification. The use of down-hole cameras has become far more readily available as the technology advances and the camera size decreases. This presentation highlights the …more

The Mystery of Unsaturated Soils

Unsaturated soil mechanics continues to play poor relation to saturated soil mechanics, in part because of the dominance of conventional soil mechanics approaches involving saturated conditions, perhaps because the inclusion of another phase (air) adds considerable complexity, and because a soil at a given density is stronger, less compressible and less permeable (i.e. performs better) …more

A Window Into Some Of The Challenges And Joys Accompanying Four Decades Of Geomechanics Practice

Andrew’s presentation will cover: salient features and “take-away” lessons from some of the geotechnical projects selected from his portfolio over the last four decades; background to the development of the Landslide Risk Management framework for Australia, dealing more with the challenges and issues in bringing the framework to fruition than specifically the guidelines themselves; and …more

Probabalistic Techniques in Geotechnical Modelling – Which one should you use?

Predictions of performance are at the core of geotechnical engineering design. Predictions based solely on deterministic analyses suffer from unquantifiable uncertainties and the implied absoluteness of the prediction. On the other hand, probabilistic estimates suffer from being vague, which is unsettling to most geotechnical engineers. Combining deterministic and probabilistic analyses offers synergies that are best …more

Field Trip: Adelaide Oval and the Riverbank Precinct

The Riverbank Precinct is one of Adelaide’s iconic spaces incorporating panoramic views across the River Torrens, the North Adelaide parklands, Adelaide Oval and Memorial Drive. The redevelopment of the Riverbank Precinct is one of Adelaide’s largest and most significant urban renewal initiatives that will see expansion of the Adelaide Convention Centre, improved pedestrian accessibility and …more
