Road tunnel ventilation optimisation using 1D modelling
OnlineOverview This event offers invaluable insights into improving road tunnel ventilation systems. Hear first-hand from experts who collaborated with Australian road tunnel operators to enhance their ventilation using advanced simulation tools. Learn how Ventsim DESIGN, a 1D network flow simulation tool with a 3D graphical user interface, was adapted for tunnel-specific challenges like jet [...]
DAARWIN-GEMINI A novel tool to predict advance rate of a TBM in real-time
Online and in person at: Level 9, 340 Adelaide Street, BrisbaneOverview SAALG Geomechanics, in collaboration with ACCIONA, has developed DAARWIN-GEMINI, a software system designed to optimize the performance of tunnel boring machines (TBMs) using machine learning-based techniques. The system key features include an advanced architecture for querying and processing data from the TBM database, big data analysis and visualization in a web browser, a [...]
Geocomposite Tunnel Invert Drainage – Online technical presentation
WebinarPresentation abstract: Cavidrain Invert geocomposite systems are used to form a drainage layer beneath the road pavement of tunnel floors. The use of Cavidrain Invert offers a number of advantages over more traditional methods (which use crushed stone and pipes) such as: (i) reduced excavation (as they form a much thinner layer compared to [...]
ITA Lecture – EPB tunnelling: environmental aspects and re-use opportunities of the conditioned muck
OnlineThe rapid development of mechanised tunnelling in the last decades has increased the tunnelling community’s focus on the environmental aspects of tunnel construction. The excavation carried out by using EPB (Earth Pressure Balance) machines often requires the use of foaming agents, specific products that are added to the medium intended to be excavated, in order [...]
Hobsons Bay main Yarra crossing duplication project
Melbourne Engineers Australia officeThe Hobsons Bay Main Sewer (HBMS), constructed in the 1960s, transfers approximately 30 per cent of Melbourne’s wastewater to the Western Treatment Plan at Werribee. The sewer alignment has a single sewer crossing under the Yarra River, which has deteriorated to a point where it requires rehabilitation and/or replacement. The Hobson Bay main Yarra [...]

Ground freezing below a river estuary – Save the date
EA Brisbane Office Level 9, 340 Adelaide St (EA Office), Brisbane, QueenslandSAVE THE DATE - Registration details coming soon Overview A new 1.48km road tunnel has been excavated beneath the Świna straits in northwest Poland using a 13.46m slurry TBM. To overcome the challenges posed by low overburden and complex geology, artificial ground freezing was implemented to enable safe excavation for the emergency egress structures [...]
