Title:	Kaiser Wilhelm Tunnel - mechanical tunnelling at the limits of experience / Kaiser-Wilhelm-Tunnel - Maschinenvortrieb im Grenzbereich der Erfahrungen
Abstract:	The subject of this article based on the Kaiser Wilhelm Tunnel is the derivation of a list of criteria for overcoming critical situations during tunnelling at the borderline of open mode to closed mode operation. The consistent application of this list of criteria demonstrates, that with knowledge of the sensitive interaction of machine and surrounding ground, the scope of application of current machine technologies can even be extended into geologically difficult areas. Formerly, this led to considerable problems, at times even economic failure of the project. The advantages the use of the catalogue of criteria has, si shown in the example of a shield machine with earth pressure components. Gegenstand des Beitrags zum Kaiser-Wilhelm-Tunnel ist die Herleitung eines Kriterienkatalogs zur Beherrschung kritischer Vortriebssituationen im Grenzbereich der Betriebsart offener Modus zum geschlossenen Modus. Die konsequente Anwendung des Kriterienkatalogs demonstriert am Beispiel einer Schildmaschine mit Erddruckkomponenten, dass mit Kenntnis des als sensibel einzustufenden Interaktionsverhaltens Maschine-Baugrund der Anwendungsbereich heutiger Maschinentechnologien auch in geotechnisch schwierige Bereiche verschoben werden kann, die noch in der Vergangenheit zu erheblichen Problemen bis hin zu einem wirtschaftlichen Scheitern des Projekts führten.
