Goal

 

NeTTUN will enable groundbreaking change in the construction, management and maintenance of tunnels in pursuit of the goals of NMP.2011.4.0-2. This is to be realised via a set of focused WPs addressing key scientific and technical challenges:

• An advanced multi-sensor ground prediction system for the Tunnel Boring Machines (TBMs) to enable fast, frequent and effective look-ahead during boring;
• A robust robotic maintenance system that enables the automation of routine tasks (e.g. inspection and exchange of drag bits and disc cutters);
•  The design of cutter tools with effective increased lifetime;
•  A novel system for modeling of global risks on tunnel projects in order to quantify and manage the many uncertainties faced during tunnelling;
•  A suite of systems for modeling and thus controlling the impact of tunnelling on surrounding structures;
•  The creation of a Decision Support system for tunnel maintenance management.

We have stated in our Description of Work to the European Commission that together, the improvements enabled by this complementary work programme will dramatically enhance every aspect of the lifecycle of tunnelling: from design, to construction, and maintenance of Europe’s already very extensive tunnel legacy.

 

NeTTUN project results will impact the tunnelling industry by enlarging business perspectives, with productivity increase; delivering underground operations with zero impact on surroundings; answering societal needs by improving safety; and strengthening competitiveness of European industry.
