E.H. Davis Memorial Lecture: Soil – Structure Interaction

Often there has been a separation in the design of foundations for buildings into the structural component and the foundation. Structural engineers have tended to use simple soil models such as springs to represent the foundation, while foundation engineers have often neglected the foundation stiffness and treated the structural as being perfectly flexible. However, it …more

Artificial Neural Networks For Settlement Prediction Of Shallow Foundations On Granular Soils

Artificial neural networks (ANNs) are a form of artificial intelligence, which, by means of their architecture, try to simulate the biological structure of the human brain and nervous system. In recent times, ANNs have been applied to many geotechnical engineering tasks and have demonstrated some degree of success. Over the years, many methods have been …more

Construction of the Suez Canal

The earliest project to connect the Mediterranean Sea and the Red Sea dates back to 1920 BC. Construction of the Suez Canal, which commenced in 1859, has had a major impact on Egypt’s modern history, as it resulted in Egypt becoming bankrupt in 1876, and being occupied in 1882 and later engaged in four wars.. …more

Site Visit: Southern Metropolitan Coastal Stability

In 2001, Golder Associates was engaged by the City of Onkaparinga to assess the risk of instability along its coastline, which runs for around 35 km from Sellicks Beach at its southern end to near the O’Sullivans Beach refinery at its northern. An inspection of the coast from a boat was used as well as …more

Young Geotechnical Engineers Night and Annual General Meeting

In 2003, three young geotechnical engineering graduates and students individually gave a 10 minute presentation on a range of interesting projects. Members of the Committee adjudicated that the 3 presenters were all worthy winners of the Award and they were each presented with a certificate and a $100 cash prize. Brendan Scott, Witton Bluff Stabilisation …more

Geotechnical Challenges and Solutions in Vancouver, British Columbia, Canada

Vancouver is one of the most beautiful and livable cities in the world and is an important port and centre for commerce and tourism. The geography and geology also make it an exciting and challenging place for geotechnical professionals. The last ice age (as little as 8,000 years ago) covered the region with a thickness …more

Brownfield Britain – Recent Experiences With Contaminated Sites in the UK

Over the last few years, the UK has seen some very significant changes in environmental legislation. In particular, this has affected the manner in which contaminated land assessment is undertaken and, consequently, the type of remediation approach that gains acceptance. Concepts such as suitability for use and harm now drive the assessment process in the …more

Slope Stability Forum

Speakers include: Dr Peter Mitchell, Dr Tony Meyers, Dr Ahmed Soliman, Richard Cavagnaro, Richard Herraman When you are confronted with a slope stability problem do you have difficulty in determining degree of slope hazard and failure mechanism? Even when you’ve got a handle on these, you’ve still got to work out the best method for …more

Collapsing Cones, Slippery Slopes, Hot Ground, Titanic Topples, Dams and Development: Engineering Geological Challenges and Models for the Active New Zealand Environment

New Zealand is a highly varied landmass with many different terrains displaying defective and difficult rock and soil masses crafted by a collection of hazardous geologic processes. This presents a unique challenge to engineering development. This talk offers a personal view of the contribution engineering geology has made to our understanding of this active New …more

Ground Improvement Techniques

Various geotechnical methods have been employed to alter the properties of soils in order to provide enhanced capacity to support “structures”, as an aid to excavation or for other purposes such as reducing water flows. These methods include vibro compaction, vibro replacement, dynamic compaction, explosive compaction, soil mixing, grouting, pre loading, sand or wick drains …more

Annual Field Trip: Port River Expressway

Construction of Stage 1 of the Port River Expressway is underway. When complete this project will contribute to South Australia’s economic development by providing new road, rail and bridge connections across the Port River, linking our export enterprises and industrial areas with key transport routes and facilities. It will also contribute to the ongoing development …more

Improving the Reliability and Effectiveness of Site Investigations

Several studies have been published over the last 30 years or so that clearly demonstrate that, in civil engineering and building projects, the largest element of financial and technical risk usually lies in the ground. Indeed, structural foundation failure, construction over-runs and delays can often be attributed to inadequate and/or inappropriate site investigations. Unfortunately, geotechnical …more

2003 E. H. Davis Memorial Lecture: Geotechnical Stability Analysis: New Methods for an Old Problem

In practice, geotechnical stability analysis is usually 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 feature …more
