Cross-passages in the TBM-tunnels of the Follobanen Project - design under high water pressures in hard rock.
Abstract: A major part of the Follobanen railway tunnel are the twin-tubes of 19 km length, excavated with TBMs almost entirely in hard gneisses. Along the segmentally lined tunnels, 80 openings are foreseen for cross-connections. Their maximum overburden is 150 m with potentially almost the same water level. The openings in the lining are 3.8 m wide and 4.55 m high.In case of high water levels, grouting...

Stability analysis of blocks formed with determined joint network – a case study of assembly chambers with...
Abstract: This paper presents the challenges of designing two assembly chambers in the Follo Line Project, EPC TBM. The chambers are required for the assembly works of the four tunnel boring machines, two machines in each chamber. These caverns are situated in hard gneiss with a depth from ground surface around 100 m in the North and 65 m in the South. The features of the assembly chambers indicate a...
