 Road tunnels and technology in an operational perspective

WTC 2017 a success!

Written by  Jun 15, 2017

His Royal Highness Crown Prince of Norway opened the World Tunneling Congress 2017 Monday the 12th of June. The theme of the congress was "Surface Challenges – underground solutions". Tunnels bind Norway together and that is all certainly true. 

The Norwegian Tunnelling society open up this event by saying:

High mountains, long fjords and steep valleys. A demanding landscape and tough climate with abundant precipitation meaning infrastructure construction in Norway is a severe challenge. This became all the more clear as road and rail started to replace the sea links that were the most important communications in the previous centuries. Yet the landscape also holds great opportunity. Many hydroelectric projects in the second half of the 20th century formed the industrialized Norway. 

The delegates got opportunity to look into tunnelling methods, projects and the history of tunnelling in Norway.

The Congress had a comprehensive program with several workshops from the ITA committees.

On the 13th of June the ITA COSUF Workshop on New Security Challenges for Design and Operation took place. This workshop was organised as part of the Congress. A definitely success when it comes to the quality of the presentations and the wide attendance from ITA COSUF members and delegates from the Congress. The topic was new threats like terrorist acts in tunnels and cyber-attacks to control systems and how these can severely influence the public life. Within this workshop on "New Security Challenges for Design and Operation", ITA-COSUF investigated how these risks can be mitigated already in the design process.

The congress session topics was:

  • Site investigation, ground characterization
  • Urban tunnelling (planning, design and construction)
  • Strategic use of underground space for resilient city growth
  • Utilization of underground for hydropower projects (unlined tunnels and shafts, underwater piercing, air cushion chambers)
  • Mechanized excavation (hard rock, soft rock and soil)
  • Innovations in drill and blast excavation
  • Large caverns (planning, design and construction)
  • Underwater tunnels (strait crossings for road and railway, utility tunnels)
  • Tunnelling for mining purposes
  • Underground waste storage and disposal
  • Innovations in rock support and water proofing technology
  • Operation and maintenance
  • Safety management of complex underground excavations
  • Stability assessment, risk analysis and risk management
  • Seismic design of tunnels and underground excavations
  • Case histories – lessons learnt

 The congress was well organised and a absolute positive experience for the tunnelling community.
