Rock Engineering Toolbox for the Follobanen Tunnels Under Existing Ekeberg Tunnels in Oslo, Norway
Just south of Oslo Central Station the new high-speed Follo Line railway tunnels pass beneath the existing Ekeberg road tunnels. This paper presents the numerical model, and monitoring program used to evaluate the stability of the E6 road tunnels during the excavation of the Follo Line tunnels at only less than 4 m below. The construction of the Follo Line was approved subject to three conditions: (1) There should be no negative effect on the stability of the Ekeberg tunnels, (2) The traffic flow in the Ekeberg tunnels must be maintained at all times and (3) Any risk of instability in the existing tunnels must be detected beforehand so that necessary precautionary action could be taken in good time. In order to deal with the challenges, SINTEF has developed a comprehensive rock engineering toolbox, combining Investigation—Numerical model—Monitoring. The tool has been used successfully in this project to provide adequate information for excavation planning and control the situation to detect any unexpected situation.
