Title:
Abstract:	In diesem Aufsatz werden auf theoretischer Grundlage abgeleitete Berechnungsansätze vorgestellt, durch die es möglich ist, das Risiko der Verklemmung des Schildmantels bei einer Tunnelbohrmaschine mit Schild (TBM-S) beurteilen und die Größe des erforderlichen planmäßigen Überschnitts bemessen zu können. Ebenso werden analytische Berechnungsansätze für den Gebirgsdruck aufgeführt, die zu einer wirtschaftlicheren Dimensionierung der Tübbingsicherung für die zuvor genannte Vortriebsart beitragen können. Dimensioning of shield tunnelling with segment lining in hard rock. In the available essay formulations based on theoretical elaborations are introduced, by which it is possible to estimate the risk of blocking of the shield skin of tunnel boring machine with shield (TBM-S) and the size of the necessary regular overcut can calculated. Likewise analytic formulations for the ground pressure are specified, with which it is possible to design an economic segment lining for the kind of driving specified before.
