51st Rankine Lecture – Geotechnical Stability Analysis

Historically, geotechnical stability analysis has been 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 can …more

Piers in Reactive Clay Soils

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

Quaking with Fear

Analysing Adelaide’s risk of a major earthquake, its likely impact and what we’re doing about it In February 2011 Christchurch experienced its second major seismic event in six months, leaving the city devastated. The magnitude 6.3 quake took 185 lives, caused billions of dollars worth of damage and prompted us to ask an unsettling question: …more

Seaford Rail Extension

The Seaford Rail Extension (SRE) project is a key objective in the State Government development plans to support Adelaide’s growing population and will improve public transport accessibility for residents in Adelaide’s southern suburbs. The SRE project is located along the coast between Noarlunga and Seaford, approximately 26 kilometres south of the Adelaide CBD. The project …more

“Geomechanics and Engineering” Australian Lecture Tour May 2012

Through the efforts of the Engineers Australia SA Division Footings Group and Dr Don Cameron, we present a lecture series by Professor Robert Lytton. This tour has been organised by the Housing Engineering, Design & Research Association (HEDRA) in conjunction with the SA, Queensland, Newscastle, Sydney and Melbourne chapters of the Australian Geomechanics Society (AGS), …more

Some Lessons From Geotechnical Failures

Dr David Tonks will discuss a number of recent significant geotechnical ‘failures’, many of which have resulted in substantial damage and cost. Some have ended up in complex and expensive litigation. Examples include construction on very soft ground, with some ongoing consolidation settlements exceeding 2 m, collapse of an arch tunnel structure during construction, movements …more
