| Abstract | SYNOPSIS: The Hida Tunnel was constructed as part of a 10.7km long highway tunnel system under the 1,000m of deep overburden. According to excavation data obtained from the excavation of a separate emergency evacuation tunnel initially built as a pilot tunnel for the main tunnel, very adverse geological conditions for a large diameter TBM excavation were identified and the most geologically challenging sections were delineated. A 12.84m diameter TBM was utilized to excavate 4.3km along the main tunnel of 10.7km. This paper focuses on possibilities for using a large diameter TBM excavation system under deep overburden conditions including criteria for the adoption of NATM excavation as an alternative. |
