• Satellite radar reveals Crossrail tunnels under London

    6 days ago - By Cellular news

    Researchers at the University of Bath have been able to use a novel form of satellite monitoring to show where Crossrail tunnels run under central London.
    Specifically, the researchers evaluated the potential of using highly detailed satellite monitoring, known as ‘Interferometric synthetic-aperture radar' techniques to assess building deformations caused by tunnelling under urban areas.
    Despite the best efforts of engineers, there will always be some level of subsidence at the surface when a tunnel is dug underneath, as the tunnel lining can never perfectly fill the space left by the...
