STUDY ON THE EFFECT OF PILOT TUNNEL BY TBM

In view of the tendency for tunnels to increase in length and cross section area, the needs for efficient new excavation methods combining mechanization and rationalization are much desired. In response to the needs, a test execution using a 3.5m diameter Tunnel Boring Machine (TBM) for a pilot tunn...

Summary:In view of the tendency for tunnels to increase in length and cross section area, the needs for efficient new excavation methods combining mechanization and rationalization are much desired. In response to the needs, a test execution using a 3.5m diameter Tunnel Boring Machine (TBM) for a pilot tunnel was planned in the construction of a Yuda No.2 Tunnel. We studied the effect of a pilot tunnel by TBM, referring to the results of the measurement data analysis by full face excavation.
