The influence of engineering geology and rock mechanics in tunnelling

  • Leopold Müller


May I conclude very shortly by making some general remarks.

One very good advice of Stini: to approach a problem from outside, proceed from totality to details.

Another good suggestion was given to me by my teacher Terzaghi who said: observe everything and try to explain what you observed! To this I would like to add: be afraid to trust too simple, plausible explanations.

May I add another suggestion: try always to combine theory and practice and to confront ideas and experience.

Furthermore: do not use follow-ups or check lists or classifications as a mental by-pass of the responsible duty of assessment, of judgments, of creative decisions! Learn from life, that contrasts are not contradictions.

Living on a star, on a beautiful home star, we should feel responsible for it, more than till now; we should feel obliged to keep it alive. Engineering geologists can do a lot in this direction.
