SUMMARY:Design of High-Performance Rock Bolted Thin Shotcrete Linings
DESCRIPTION:Design of High-Performance Rock Bolted Thin Shotcrete Linings\nFrom Basics to Advanced Concepts\nOverview\nTunnels in poor to fair-quality rock masses (i.e. Q-values between 0.4 and 10) can generally achieve global stability and ground support primarily through ground reinforcement\, such as rock bolts. Such reinforcement elements not only hold unstable rock wedges and blocks but also provide local shear and tensile reinforcement where they cross rock defects or discontinuities\, enhancing the rock mass’s capacity to redistribute stresses during tunnel excavation more safely. However\, to keep costs down\, rock bolt spacing must also be efficient; as a result\, the use of a surface retention system\, such as shotcrete\, is still necessary to promote local stability and stress arching\, thereby supporting the rock mass between the rock bolts. In these cases\, a thin shotcrete lining (75-150 mm thick) is often used. It is usually designed to span the loads between the rock bolts\, accounting for both flexural and punching failure mechanisms. When combined with long cables\, as it is frequently used in mining\, the system can also play a greater role in global stability\, reducing the risk of larger failure mechanisms with volumes of the order of the excavation. It can\, in principle\, also be designed for dynamic loads if the bolts are designed for them. This presentation will discuss some basic concepts of this support system\, including the use of fibre reinforcement\, and then move on to more advanced concepts\, such as compressive membrane action and non-linear concrete design. \nSpeaker\n\n \n\nDr David Oliveira \nDiscipline Leader\, Ground\, Aurecon \n\n\n\nDr David is a Chartered Professional with 27 years of experience in civil engineering and mining geomechanics. He is Aurecon’s Discipline Leader for Ground Engineering\, including the Geotechnical\, Geology\, Tunnels\, Underground Structures and Pavements teams. He is also currently the Vice-Chair of Working Group 12 – Sprayed Concrete of the International Tunnelling Association. Besides major recent infrastructure such as Westconnex M8\, Westconnex M4-M8\, Hinkley Point C Nuclear Power (UK)\, Sydney Metro West-Central Tunnelling Package\, Western Harbour Tunnel Package 2\, and Borumba Pumped Hydro\, David has worked in projects for some deep underground mining projects such as Gwalia Mines (AU)\, Big Gossan (Indonesia)\, Cuiaba Mine (Brazil) and currently Oyu Tolgoi (Mongolia). \n\n\nThis event is run by the Australian Geomechanics Society in collaboration with Western Australian Ground Control Group and Australian Tunnelling Society. \n\n\n

SUMMARY:Umbrella canopy tubes in tunnel construction
DESCRIPTION:Overview\nThis event explores umbrella canopy tubes as a pre-support solution for tunnelling in unfavourable ground conditions. Fundamental understanding of the structural mechanics of canopy supports will be developed through the investigation of overburden loading on tunnel boundaries\, failure mechanisms of umbrella canopy tubes and ground material\, and monitoring systems for tunnels.   This theory will be applied to determine analytical solutions for simply loaded umbrella canopy tubes. From these findings\, the performance of umbrella canopy tubes on a Project will be investigated to validate the analytical solutions and provide context to theory.  Who should attend? This event is ideal for civil and geotechnical engineers\, tunnelling specialists\, and professionals involved in underground construction and infrastructure projects. It will also benefit those working in design\, analysis\, and monitoring of tunnel support systems\, as well as anyone seeking to deepen their understanding of ground behaviour and structural mechanics in challenging conditions. \nProgram timeline\n5.30 PM AEST – Registration and catering \n6.00 PM AEST – Event begins \n7.00 PM AEST – Event concludes \nLearning outcomes\nIn this presentation you will learn: \n\nUnderstand load distribution from overburden ground pressures onto umbrella canopy tubes.\nIdentify failure mechanisms and determining success of umbrella canopy tubes.\nDetermine effective application of monitoring systems in tunnels.\n\nAbout the speaker\n\n\n\nKate Burger\nGraduate Geotechnical Engineer\, AECOM\nKate attended the University of Queensland and works at AECOM as a Graduate Geotechnical Engineer. Kate is the winner of the ATS Tunnelling Student Award 2025.\n\n\n\n\n\n\n\n\n\nArun Sarathchandran\nPrincipal Geotechnical Engineer\, AECOM\nArun attended Delft University of Technology and works at AECOM as a Principal Geotechnical Engineer.

SUMMARY:Design and construction of Cross River Rail tunnels
DESCRIPTION:Overview\nUrban metro rail tunnels often involve shallow alignments through variable ground conditions\, in proximity to existing buildings and infrastructure. The construction of large underground spaces for railway platforms\, services\, and mechanical and electrical plant adds significant design complexity. The Cross River Rail project provides a compelling case study\, demonstrating how engineering solutions can overcome these constraints in a densely developed city environment. \nThis event will present the technical approaches used to address the geological and geotechnical challenges encountered during the design and construction of the four station caverns and twin mined tunnels. Participants will gain insights into the design considerations for excavation\, primary support\, and permanent lining\, as well as how the project team navigated risks associated with ground variability\, urban settlement\, and structural interface with existing infrastructure. The session will highlight practical lessons and solutions relevant to tunnelling and underground structure design. \nLearning outcomes\nIn this presentation\, you will learn: \n\nhow Brisbane’s geology influenced the design and construction of Cross River Rail caverns and tunnels\nthe key engineering challenges encountered and how they were addressed in cavern and tunnel design\ndesign considerations for excavation\, primary support\, and permanent lining in urban tunnelling projects\nhow design outcomes mitigated risks and informed practical solutions for large-scale underground construction.\n\nProgram\nIn-person: \n\n5.30 pm AEDT: Registrations open\n6.00 pm AEDT: Presentation begins\n7.00 pm AEDT: Q&A session\n7.30 pm AEDT: Event ends\n\nAbout the speaker\n\n\n\nAdrian Smith MIEAust CPEng NER\nPrincipal Geotechnical Engineer\, PSM\n\nAdrian Smith is a Principal Geotechnical Engineer at PSM with more than 20 years’ experience in a variety of geotechnical practice areas including design and construction of rail and road tunnels\, and underground and open cut mining. \nHe was PSM’s Design Director for the Cross River Rail project from tender stage through to construction\, overseeing the geotechnical and hydrogeological interpretations\, ground-structure interaction\, and design of temporary and permanent support for all mined running tunnels and four underground station caverns.
