The influence of a designed twin-tube highway-tunnel on the stability of a nearby water-transmission tunnel

  • A tunnel is not only stabilized by safety measures e.g. steel and concrete. The surrounding underground is part of the construction. The excavation of an underground opening influences the stresses around the tunnel. Therefore twin tube highway-tunnels are excavated in a distance 40 m. When the designed tunnel meets ex isting underground structures in a smaller distance the impact of the stress changes is to be investigated. For the investigated case w here the new tunnel crosses the ex isting tunnel in a distance of only 7 m the stress changes required extra safety measures for the existing tunnel.
