Title:	Real time process controlling for EPB shields / Echtzeit-Prozesscontrolling bei Erddruckschilden
Abstract:	The contribution gives an overview of the state-of-the-art of process controlling in mechanised tunnelling. A web-based and ubiquitous integrated database forms the backbone of PROCON II, a software for the analysis of machine data, project specifications, shift reports and geodetic information stored in a temporally and spatially correlated data structure. The software helps to build a knowledge base that is fed by experience from the present as well as all previous projects and that helps optimising safety, efficiency and performance of a mechanised tunnelling project. Along with a brief summary of the program features of PROCON II, this contribution gives three examples of how the software can be employed to gain insight into the key mechanisms of Earth Pressure Balanced (EPB) shield tunnelling and how it can help to improve the tunnelling performance. Der Beitrag gibt einen Überblick über den Stand der Technik des Prozesscontrolling im maschinellen Tunnelbau. Eine webbasierte und überall verfügbare integrierte Datenbank bildet das Rückgrat von PROCON II, einer Software, welche die Analyse von Maschinendaten mit Projektspezifikationen, Schichtprotokollen und geodätischen Informationen in einer räumlich und zeitlich korrelierten Datenstruktur verknüpft. Die Software unterstützt dabei den Aufbau einer Wissensbasis, die auf Erfahrungen aus dem laufenden sowie aus vorangegangenen Projekten beruht, und dabei hilft, die Sicherheit, Effizienz und Leistungsfähigkeit eines maschinellen Tunnelvortriebs zu optimieren. Neben einer kurzen Übersicht über die Programmfeatures von PROCON II beinhaltet dieser Beitrag drei Beispiele, wie die Software eingesetzt werden kann, um am Beispiel eines Erddruckschildvortriebs Einblicke in Schlüsselmechanismen zu erhalten, und wie sie dadurch helfen kann, die Vortriebsleistung zu verbessern.
