The authors are investigating the ground conditions concerning TBM excavation to make clear the geologic factors affecting TBM feasibility, to estimate the relation between rock mass properties and the rate of penetration of TBM and also to establish the way how to proceed geologic survey for tunneling with TBM. Few investigations have been reported to estimate TBM feasibility through variety of investigations considering the effects of discontinuities as well as strength and hardness of rock mass. Artifitial factors affect considerably on tunneling with TBM, therefore the investigation and consideration on the TBM feasibility in relation to ground conditions seem to be very hard work. Some basic relations between geologic factors and TBM feasibility are introduced here, and following reports will be published soon after to comment it in detail.
