... along existing discontinuities and subsequent dilation. The amount of dilation will depend on the energy release characteristics of the rock mass. The success or failure of a tunnel design may therefore be demonstrated through the deformation behavior of the surrounding rocks. Inherent in this concept...

... promises that are imprecise, vague, or open-ended. The success of such a system depends on the ability to extract information from geology, rook mechanics, and tunnel technology and translate it into a form or forms which help the user to make a more intelligent decision for tunnel design. Potential...
