2013 Victoria Meetings

E.H. Davis Lecture

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

Advances in Piling Techniques and Design

The introduction of limit state analyses has required that all pile designs include calculations not only for geotechnical strength but also for serviceability. This has resulted in more rigorous calculations that in turn have forced the geotechnical profession to consider pile performance in a more thoroughly and has led to a better understanding of pile …more

John Jaeger Award National Tour

Contrary to the popular view of geothermal energy, shallow geothermal systems make use of the ground at normal temperatures within a few tens of metres of the surface as a heat source in winter and a heat sink in summer to heat and cool buildings. A ground source heat pump or GSHP, in combination with …more

YGP Jack Morgan Award Presentation

The Jack Morgan Award is presented biennially to an outstanding Victorian geotechnical practitioner under the age of 35. This year, three applicants have been shortlisted to give 20 minute presentations on their chosen topic and an expert panel will judge each candidate on their contribution to geotechnics and understanding of geotechnical issues. The winner will …more

52nd Rankine Lecture (2012): 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

Use And Abuse Of Springs To Model Foundations

Springs are widely used in structural modelling packages to represent the stiffness response of foundations. This method is a significant improvement on models which assume the foundation is a rigid fixed or pinned support, and assigning a foundation stiffness is essential to enable structural models to better identify load re-distribution and deflection induced stresses in …more

Low level construction vibrations in residential structures

The first part of the presentation will examine the response of residential structures to low level vibrations by reviewing a comprehensive experimental program, which included a unique shaking-table study of a full-scale single-storey brick-veneer house subjected to 500+ vibrations, with Peak Particle Velocities (PPVs) ranging from 0.2 mm/s to about 400 mm/s (with interesting observations). …more

Geothermal Energy: to heat and cool buildings

There is a form of geothermal energy which makes use of the ground at normal temperatures within a few tens of metres of the surface as a heat source in winter and a heat sink in summer to economically, efficiently and sustainably heat and cool buildings. These systems go by a variety of names including …more

University Research Student Presentations

Research students from our Victorian institutions will give a short talk on their research projects throughout the technical meeting. The main objective is to let the AGS members know about some of the current research and development studies being undertaking in Victoria, and to share and discuss R&D needs and ideas. Topics and speakers are …more

Technical Field Trip: Western Port

That Sinking Feeling… Western Port: highs and lows in a tectonic embayment The Western Port embayment is generally a low-lying area bounded by the Mornington Peninsula to the west and the South Gippsland highlands to the north and east. The landforms that make up the embayment initiated in response to tectonic activity during the Tertiary, …more

ATS: Tunnelling Under Sydney Opera House

The Sydney Opera House Vehicle Access and Pedestrian Safety (SOH VAPS) project is a $110 million project being completed by the Sydney Opera House Trust. The main goal of the project is to remove service vehicles from the forecourt of the entertainment precinct which receives close to 10 million visitors each year. It involves the …more

Ground Engineering and the Law

Nick will follow up the presentation he delivered last year. He will discuss new topics such as negligence claims and the use of dispute resolution boards to resolve large engineering disputes, as well as revisiting, in light of recent case law, some of the topics he covered last year, such as expert evidence and proportionate …more
