90 day tunnel wall convergences at 2 example measurement sections C4 (left graph) and C7 (right graph). C4 was located in the shotcrete section of the FE tunnel at ‘tunnel metre’ (TM) 27.6 and C7 was located at TM44.2 in the shotcrete-free section supported only by steel sets. The scale of the displacement vectors is amplified by a factor of 20 with respect to the excavated tunnel represented by a black circle. The right side of each graph represents the north-western side of the FE tunnel
