2019 SA-NT AGS Seminar, call for abstracts


The South Australian-Northern Territories Chapter of the Australian Geomechanics Society (AGS) and the Australian Tunnelling Society (ATS) are pleased to announce the 2019 AGS Seminar titled “Tunnelling under Adelaide” which is to be held on Monday 28th October 2019.

The seminar forms part of the continuing programme of events organised by the SA-NT Chapter of the AGS and aims to provide the engineering profession with a comprehensive introduction to the geotechnical aspects of tunnelling in soil in urban areas, including best practice techniques and recent developments.

For more information see the Call For Abstracts flyer.

The Event

South Australia has seen significant investment in transport infrastructure in recent years. The development of a dedicated non-stop North-South Corridor for Adelaide is a direct result of a strategic objective to reduce Adelaide’s urban road congestion. The North-South Corridor is one of Adelaide’s most important transport corridors and is the major route for north and southbound traffic including freight vehicles running between Gawler and Old Noarlunga, a distance of some 78 km. Many of the associated projects involve complex geotechnical challenges.

The South Australian Government is currently considering the viability of tunnelling options for the two remaining sections of the strategic North-South Corridor between River Torrens to Anzac Highway and Anzac Highway to Darlington and plans to submit a business case that includes tunnel options to Infrastructure Australia for review. Design and construction of the remaining sections will be the biggest single infrastructure project in South Australia’s history.

This seminar will present overviews of current design practice, state-of-the-art practices, novel technologies and innovative solutions, and case studies demonstrating applications of advanced techniques and cost-effective solutions in the design and construction of TBM tunnels in clay, with a focus on the geotechnical challenges associated with the completion of the North-South Corridor between the River Torrens and Darlington.

The seminar will bring together professional engineers, researchers, specialist contractors, regulators, educators and students to share and discuss their experiences on the topic of the design and construction of TBM tunnels and their associated challenges and opportunities.


The following are some suggested topics for the Seminar:

Planning and Investigation

  • Contract models
  • Risk management and Health & Safety
  • Ground investigation strategy and techniques
  • Tunnel alignment design
  • Ground hazards
  • 3-D geotechnical models and digital engineering
  • Geotechnical Baseline Reports

Geotechnical Design

  • Segmental and shotcrete lining design
  • Tunnel induced ground movements and their impacts on existing infrastructure
  • Instrumentation and monitoring
  • Ground treatment

Excavation and Construction Methods

  • TBM selection and performance
  • Cross passage design and construction
  • Shaft sinking
  • Crossover structures
  • TBM launch and reception pits
  • Groundwater control
  • The role of tunnel engineers during construction and the use of the observational method


The SA-NT Chapter of the AGS, in conjunction with the ATS, invites local, national and international practitioners to submit abstracts on a topic related to the design and construction of TBM tunnels in clay. Abstracts are not to be more than 300 words and shall be prepared in accordance with the abstract submission guidelines outlined below. Completed abstracts should be sent to Abbas Taheri by Monday 20 May 2019 for consideration by the seminar organising committee.

Abstracts will be selected based on their quality and relevance to the theme and objectives of the seminar with the successful authors invited to submit a six-page paper for presentation at the seminar. We encourage submissions from the geotechnical engineering and tunnelling professions as well as academia.


The cost of the seminar is to be confirmed. Presenters will enjoy free entry to the seminar with discounts for co-authors.
