ABSTRACT
Since our first contacts with the D2 Consult company ten years ago, our institute became interested and, with the growing intensity of our cooperation, fascinated by the new technologies in tunnel construction. Our own background is computer mathematics and software, in particular “symbolic methods” and part of our research is quite abstract. I remember that, at the beginning, it took me some effort to convince my young co-workers to engage in mathematics-based design and implementation of software for simulation and control of tunnel planning and tunnel construction. Meanwhile we went through a couple of quite successful projects in this area in a long-lasting and fulfilling cooperation with D2 Consult. Some of the researchers at our institute became deeply involved in the challenging mathematical and software-technological problems of tunnel engineering.
