Cone Penetration Tests in Unsaturated Soils Mohammad Pournaghiazar, University of New South Wales The Cone Penetration Test (CPT) is a widely used in situ test. CPT data are used to evaluate the engineering properties of soils based on a number of correlations proposed for saturated or dry soils. However, no such correlations currently exist for …more

Newcastle geology: 250 million challenges for the engineering geologist

This presentation will outline classical aspects of the geology of the Newcastle region, concentrating on the Newcastle Coal Measures, and how various aspects impinge on the work of engineering geologists. The presentation considers stratigraphic variation, including the unusual occurrence of conglomerates, and sedimentary variation, notably the occurrence of expansive clayrocks; tectonics, mainly through the examination …more

Lessons from the Yallourn Batter Failure Inquiry

The Northern Batter of the Yallourn Mine collapsed at approximately 2:00am on 14th November 2007. The collapse diverted the Yallourn River into the mine, resulted in the immediate loss of one fifth of Victorias Power Generation capacity and cost the mine over $200 million. Because of the environmental and infrastructure damage, the Victorian Government decided …more

A Framework For Forensic Engineering

Co-hosted with EA Civil/Structural Branch, EA Engineering Practice and ASCE Australia Section Forensic geotechnical engineering is gaining increasing importance in many countries where foundation failures may lead to litigation and even criminal action. This lecture describes a relatively simple framework for investigating the possible causes of foundation failures in a systematic manner. Attention is confined …more

Calculation of heave of deep pier foundations

Design of pier and grade beam foundations in highly expansive soils is one of the most important and challenging aspects of geotechnical engineering. Existing design methods consider only uniform soil profiles, and piers with limited length to diameter ratios. These methods are restricted with regard to evaluation of more complex aspects of pier heave. A …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

E.H. Davis 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

Deficiencies In Current Liquefaction Criteria As They Apply To Western Australia

In many parts of the world, including Australia, the state of practice in assessing if liquefaction will occur is based on the recommendations of Youd et al (2001) which arose from workshops convened in the United States by NCEER. However, the final publication did not so much represent a consensus view as a compromise between …more

Designing for Rockfall: According to the guidelines for the approval of Rockfall Protection Kits

There is a trend in Australia of infrastructure projects occurring in higher developed areas which result in more road and railway cuttings with steeper slopes. The weathering processes on these slopes can cause rockfall which has the potential to harm road or rail users, and cause disruption to these essential services. Therefore, the protection of …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
