Probabilistic limit-state approach for predicting the useful life applied to rock bolt corrosion.
Some rock bolts used as permanent rock supports in Norwegian road tunnels. a Uncoated rebar cement grouted in the Haukeli road tunnel constructed between 1968 and 1969. The rebar is 20 mm in diameter and 2.4 m long (Pedersen and Hafsaas 1991). b Pipe bolt used in Byfjord and Mastrafjord subsea road tunnels constructed between 1989 and 1992. The 3-m-long rock bolt, steel pipe and accessories are hot-dip galvanized and epoxy coated (Espedal and Nærum 1992). c CT-Bolt used in the Frøya subsea road tunnel constructed between 1998 and 2000. The 3-m-long rock bolt, rebar and accessories are hot-dip galvanized and epoxy coated (Holmøy et al. 2009)
