Future of geotechnics: Disrupting tunnelling
The engineers behind the new Hypertunnel method aim to shake up the tunnelling status quo.
Underground construction innovations through the ages range from drill and blast – introduced to mining in the 1600s – to Marc Brunel’s tunnelling shield used to build the Thames Tunnel between 1825 and 1843.
This was followed by the introduction of mechanical tunnelling machines, and, roughly a century later in the 1950s, an early version of the modern tunnel boring machine (TBM).
