ON THE CHECK SYSTEM FOR GEOLOGICAL SURVEY OF TUNNELS

Development of engineering practices in tunneling has gradually reduced the range of geologic conditions which make construction works impossible. Therefore, for the higher reliability a pre-estimation of geologic conditions has come to be demanded. In each stage of geological surveys, the following items should be included where the surveys are correspondingly stepped up. What subjects are clear and what are not? What subjects must be examined next? What methods are there to examine these? Consequently, data for execution schedule of the construction and criteria on results of geological surveys are summarized.
