COMPUTING 3-D KEY BLOCKS DELIMITED BY JOINT TRACES ON TUNNEL SURFACES

The application of the newly developed computer code for analyzing 3-D maximum key blocks from joint traces on tunnel surfaces are illustrated by two practical examples. The code was developed to improve the practical application of key block theory. It includes the computation of maximum key blocks by using hypothetical joints generated from statistical data and actual joint traces mapped in the field. Based on the results of this study, the code appears rational and practical. However, further development in the measuring techniques for obtaining the actual joint information in the field may be required. (A) This paper was presented at the 34th U.S. Symposium on rock mechanics, 27-30 June 1993, University of Wisconsin-Madison. For the covering abstract see IRRD 863389.
