  Launching structures for tbm tunnelling. Design and purpose

  Abstract: Different TBM launching structures can be designed for different situations and projects, depending on many factors. The constructability of those structures and many other constrains related to the safety and functionality, must be taken into consideration during the design to fulfil their purpose. Collecting many types of TBMs experiences and different TBM launching requirements, some...

  TBM Hard Rock Tunnels ProjectsPenetration Rate Comparison Between

  Abstract: One of the biggest tunnelling technical challenges when considering long hard rock tunnels is the estimation of the production expected in the project and how to get precise penetration and advance rate predictions. An accurate advance rate estimation (by basic calculations) as close as possible to the real future performance, mostly in long tunnels, is a key element for rock tunnel analysis...
