Effects of ground water pressure on the surrounding of cross passage openings through segmental concrete linings
Abstract: The main tunnels of the Follo Line Project will be built by shielded TBMs using a water tight segmental lining, while the most of the cross passages are foreseen to be drained. The segment ring and the collar, which supports the opening of the segmental lining, will constitute an undrained lining, but the ground water pressure in the rock mass around will be modified by the water flow towards...

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...
