A STUDY ON TBM MECHANICAL DATA ANALYSIS METHODS

In the Hida Tunnel, which is 10700 metres in length, it is planned to apply a Tunnel Boring Machine (TBM) with phi = 12.84 m to the excavation of the main tunnel in its whole section and start its operation in autumn 2000. Thus, the mechanization of the tunnel excavation work using TBM is now rapidly progressing in Japan Highways. The following problems should be studied more deeply in order to obtain successful TBM performance: (1) How to properly judge the feasibility of TBM application to a tunnel excavation in the planning stage; (2) How to properly evaluate the mechanical properties of rock mass based on the TBM mechanical data and reflect them in the design of the tunnel supports; (3) How to predict the zone where TBM may have difficulty in progress during the work by using TBM mechanical data; (4) How to select proper measures when TBM progress has become impossible. This paper provides the basic materials necessary for studying particularly problem (2), and also shows some viable, simple analysis methods by way of example for analyzing the TBM mechanical data at work sites in anticipation that such data will be generated in large quantities from the tunnel excavation work where TBM is operated.
