Failures in Dewatering for Diaphragm Wall (and Similar) Deep Excavations
Abstract Many failures have been recorded globally, in deep foundation excavation works within diaphragm wall or similar enclosures relating to water inflow. The issues appear to be relatively straight forward – so why is the industry getting this wrong? Examples of failures are presented, primarily from the presenter’s experience investigating dewatering problems in the Middle More Information…

The evening will include a 3 course banquet created especially for this occasion More Information…
Well, what is the strength of unsaturated clay?
Talking Points There are several equations for the shear strength of unsaturated clay. Which is best? How do you get the numbers to put into them? How do you use them for design? This talk is a journey, starting with a trip down memory lane, traversing steep cuttings while retaining a sense of humour, then More Information…
Laboratory Testing of Expansive Soils Seminar
Who Should Attend and Why? Identifying and managing the risks associated with problematic soils is essential for the geotechnical engineer. Across much of metropolitan Adelaide, the presence of expansive clay soils means that practising geotechnical and structural engineers need to have an awareness and understanding of the requirements for specifying, undertaking and interpreting laboratory testing More Information…
Young Geotechnical Professional’s Event
Showcasing Young Geotechnical Professionals & Students The July meeting of the South Australian Chapter of the Australian Geomechanics Society will consist of presentations by young geotechnical professionals and students. The meeting will follow the format of the ten previous Australian and New Zealand Young Geotechnical Professionals Conferences. Meeting Aims To enhance professional development by sharing More Information…
A Systems Approach to Verifying Driven Pile Foundations
Talking Points Over the past 30 years, dynamic pile testing (PDA) has become a generally accepted technique for verification of driven pile capacities in Australia. In the vast majority of projects, the technique is specified as a quick, inexpensive and generally reliable method for proof load testing for contractual verification. That being said, the implementation More Information…
Seepage, Erosion and Piping.
Abstract “It’s not the soil that causes problems in geotechnical engineering – it’s the water in the soil”. This statement was made to Matthew Duthy by one of his former bosses, and it has stuck in Matthew’s head ever since. Water in soil causes a number of problems in geotechnical engineering, but the focus for More Information…
AGM, Chair’s Address, Annual Dinner and Guest Speaker
The Victorian Chapter of the Australian Geomechanics Society invite you to their Annual General Meeting on Wednesday 25 November, followed by their Annual Dinner. During the AGM the outgoing chair Jeremy Barber will give a presentation and we are proud to welcome Associate Professor Stephen Gallagher of the University of Melbourne to talk to us More Information…
Joint AGS/Structural Meeting:
Residential Slabs on Reactive Soils
Abstract Site classification is the key to a successful design, however it is fraught with uncertainty, partly because of the economics of house construction. The classifier must use judgement and available knowledge to classify a greenfield site. Then there are earthworks to consider, which may alter the classification. Designers need to be aware of the More Information…
Recent developments in earthquake seismology
Abstract The past few years have seen a significant increase in earthquake activity in the Western Strzelecki Ranges of West Gippsland. This activity and it’s implications will be discussed. Other local developments include a study on the relationship between earthquake and volcanic activity in western Victoria. These studies rely on higher resolution seismograph coverage than More Information…
Challenges of New Metro Station and Associated Tunnel Construction in a Mature Urban Environment: New Bugis Station
This is proudly brought to you as a joint presentation by AGS Victoria and the ATS. Abstract The expansion of mass transport systems in Asia requires new infrastructure to be built around, above and below operating networks. These conditions, along with tight environmental controls necessary for work carried out amongst high population density areas, requires an unprecedented More Information…
54th Rankine Lecture (2014):
Interactions in Offshore Foundation Design
Abstract Offshore foundation design has been a research topic with direct practical applications for a number of decades, with the increasing need to generate power by harvesting offshore wind presenting new challenges. The lecture will use examples from offshore foundation design to illustrate important areas: (a) where geotechnical engineers need to address engineering problems in More Information…
Geotechnical Instrumentation and Monitoring
Abstracts Geotechnical Instrumentation: Principles and Remote Monitoring – Stephen Darmawan The presentation will cover the principles of geotechnical instruments and the common sensors widely used in civil construction and infrastructure projects. There will be discussion on the criteria of having an automated real time monitoring system versus the traditional in situ observational methods. The systems More Information…

An improved methodology for the determination of design groundwater levels for civil construction projects
Presented by AGS WA with the International Association of Hydrogeologists Speakers: Dr. Anastasia Boronina & Russell A. Clayton Abstract Design Groundwater Levels or “reasonable maximum” groundwater levels are required for the design of civil structures, such as pavements and baths structures and detention basins. In particular, the groundwater levels will impact the height of the More Information…
The design and construction of the 16 hectare basement at Marina Bay Sands, Singapore
ABSTRACT Singapore’s newest integrated resort, Marina Bay Sands, was completed in record time and has garnered numerous engineering awards. The development sits on recent sand reclamation, which in turn rests on deep soft marine clay deposits. With an average excavation depth of around 18 metres, the 16 hectare waterfront development involved some of the largest More Information…
