Evaluation of Soil Liquification and Post-Earthquake Deformation using CPT

The presentation will provide a brief background on soil liquefaction and describe how the Cone Penetration Test (CPT) can be used to evaluate the potential for liquefaction as well as estimate post-earthquake deformations. Example case histories will be used to illustrate the methodology. The presentation will compare and discuss recent CPT-based methods.

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. These techniques have the major disadvantage of the need to presuppose an appropriate failure mechanism. This can lead to inaccurate predictions of the true failure load, especially for cases involving layered materials, complex …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

Refinement of the Conceptual Ground Model for Melbourne Metro

Members and visitors are invited to a presentation on the ongoing refinement of the conceptual ground model for the proposed Melbourne Metro rail tunnels. Anthony Bennett, from the Public Transport Victoria’s Technical Adviser team, will set the context of the project, outlining the proposed new rail link beneath North Melbourne, the CBD, and St Kilda …more

Liquefaction Hazard in Australia

The Canterbury Earthquakes of 2010 and 2011 caused tremendous damage to the City of Christchurch and its surrounding areas. Aspects of the earthquakes are well documented, including the seismology as well as damage to land and structures within the CBD and suburbs. In the two years since the first earthquake occurred in September 2010, a …more

Sustainable Resilient Ground Engineering

The pressures of urbanization place demands on city infrastructure and connections between cities. The rapid urbanization in the latter half of the 20th century was carried out against a backdrop of depletion of limited natural resources, generation of wastes, including greenhouse gases, and inefficient use of energy. The Bruntland Commission and subsequent report of 1987 …more

Groundwater Issues Related to Tunnelling

Dr Harry Asche will illustrate the importance of hydrogeology in tunnel planning, design and construction. He will also discuss the fundamentals of hydrogeology; the tools used by hydrogeologists to define and identify the critical parameters; how to make sense of the data; and “tips for tunnellers”. Mike Dudding will talk about groundwater inflow measurements, during …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

Management of a Highway Pavement for Subsidence Impacts from Longwall Mining

The first of a number of planned longwalls directly beneath a freeway, southwest of Sydney has been completed. After a lengthy planning period, the risks to the highway pavement were successfully managed by the road authority, the mining company and a Technical Committee including specialists in the fields of pavement engineering, geotechnical engineering and subsidence. …more

AGS Foundation Training Series: Laboratory Testing, Theory and Practical Application

“Mistakes and Problems with Laboratory Testing” The course aims to provide information on geotechnical laboratory testing methods to professionals working in the civil and mining industry. Although the subject is often taught during formal education, the actual implementation of that knowledge is not always straight forward. Some of the issues that will be covered in …more
