Modelling Cover Systems for Waste & Unsaturated Soils Mechanics in Engineering Practice

One of the most active unsaturated soil mechanics applications over the past two decades has been the design of cover systems associated with mine wastes; particularly “store and release” (or evaporative) covers. Cover systems appear to be a success story for unsaturated soil mechanics; however, it is time to stop and ask the question, “Are …more

Eureka Tower, A Bored Pier Foundation Story

The Eureka Tower Project is a 300 m high 88 level residential building, constructed in the Southbank precinct of Melbourne, Australia. The site is underlain by complex geology, including near surface soft clays, a shallow layer of Quaternary Age basalt which covers part of the site, a lower very high strength basalt layer at about …more

Deep Foundations, Excavations and Retaining Walls in South Australia

We are all aware that much of the soil in the greater Adelaide Metropolitan area excavated for deep foundations, excavations and retaining walls is unsaturated clay. The strength, stiffness and volume of these clays are greatly influenced by their suction which, in turn, is affected by environmental conditions. These characteristics necessitate a different approach to …more

Rankine Lecture Tour: Soil-environment interactions in geotechnical engineering

The range of problems that geotechnical engineers must face is increasing in scope and complexity. Some examples are the collapse of unsaturated soils, foundations on expansive clays, tunnelling in sulphate bearing materials, control of subsidence due to oil or gas extraction, and containment of toxic or hazardous waste. In addition, potential climate change may pose …more

Golder Associates Night: Soil Nailed Retention Design And Application

Soil nailed retention was first used overseas in France in 1972, and has since been used widely in Europe and the United States. It has been used in Australia on a number of road and freeway projects and building sites since the early 1990’s. Ivan will present a historical review of the use of soil …more

Screw Pile Anchors

Screwpiling has been used since the early 1990’s in Australia. Screwpiling is not new having been used in England in the 1830’s and in Indonesia by the Dutch in colonial days. Screwpiles can be used in piled foundations as an alternative to other piling systems. However, the strength of screwpiles is often limited by the …more

What Is Failure And Why Do Failures Occur?

Ground engineering is a risky business; there is much that can, and does, go wrong. Failures of construction in the ground can be more than just slips, excessive settlement or flooding. Sometimes failure of the ground is a requirement of the design. The talk will consider the nature of geotechnical failures in a wide sense. …more

Deep excavations in soft ground using temporary structural steelwork

In many city areas, ground anchors and soil nails cannot be used for deep excavation retention in soft ground due to construction constraints including adjacent structures. A solution often used I braced excavations involving temporary structural steelwork, serving multiple functions, like strutting, waling, lagging, traffic and construction decking. Based on Chris’s design and supervision experience …more
