It is said that the TBM technique will be applied more extensively in Japan. Such prediction refers to these facts: tunnel boring machines applicable to various geological conditions in our country have been developed, and a practice using a TBM is now being studied, for cutting a drift of an extremely large section tunnel. In this context, it is essential to develop an automatic direction control system of TBMs, when considering high-level skill required for operation of TBMs and a great amount of time needed for training of skilled operators.
The system discussed in this paper has been working for a TBM for "construction of the Tsukui headrace tunnel" (TG540-manufactured by Komatsu) since October 1995.
