Development of Underground Tunnel Construction Technology in Weak Rock
Abstract The construction of tunnel has a long history from the mining tunnel for minerals to underground passage for transportation. Most of tunnels are being constructed to pass through the high mountain to have a shortcut instead of taking a detour to reach the destination. The geological conditions in the area of tunnel construction work are not all the time favorable condition. The rock bolt and steel rib support systems for tunnel face are described. The tunnel construction in weak rock is described with rock bolt and steel pipe grouting reinforcement (NATM). The advantages and construction procedures of pre-supported tunneling method (PSTM) and tubular roof construction method (TRcM) in soft ground are presented with the detail schematic diagrams. In the latter part of this paper, the field application case histories of PSTM and TRcM are reported for the tunnel construction for road in weak rock and metro station in soft ground, respectively. The field monitoring results during the tunnel construction which underpass through 60-m-long existing railway tracks by using TRcM are also described.
