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, Brisbane

Overview 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 ground-machine ...

ITA Lecture – EPB tunnelling: environmental aspects and re-use opportunities of the conditioned muck

Online

The 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 to ...

Hobsons Bay main Yarra crossing duplication project

Melbourne Engineers Australia office

The 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 crossing ...

ITA Lecture – Practical Aspects of Segmental Tunnel Lining Design

Webinar - Online only

Topic: Practical Aspects of Segmental Tunnel Lining Design After several decades of continuous progress, mechanized tunnelling has now become the main method applied in almost all types of geology, all sizes, and in increasingly shorter lengths. The predominant excavation support system for TBM tunnels consists of a one-pass precast concrete segmental liner which in addition ...
