Die Anwendung von Building Information Modeling (BIM) im Infrastrukturbau soll bis zum Jahr 2020 in Deutschland eingeführt und anschließend etabliert werden. Dies schließt auch die Planung, die Herstellung und den Betrieb von Tunnelbauwerken ein. Im Rahmen von Forschungs‐ und Praxisprojekten wurden in den letzten Jahren bereits Erfahrungen zur Verwendung der BIM‐Methodik gesammelt. Es hat sich gezeigt,...
Mechanized tunneling is one of the most common methods used for underground constructions for infrastructure systems. Since a tunnel boring machine (TBM) represents a non-redundant single machine system, the efficiency of maintenance work highly impacts the overall project performance. The wear and tear of cutting tools is a critical, but mostly unknown process. To plan the maintenance work of cutting...
Reconfigurable fine-grain electronics target an increase in the number of integrated logic functions per chip by enhancing the functionality at the device level and by implementing a compact and technologically simple hardware platform. Here we study a promising realization approach by employing reconfigurable nanowire transistors (RFETs) as the multifunctional building-blocks to be integrated therein...
The planning of mechanized tunneling projects requires the consideration of complex constraints and project objectives. Process simulation provides a tool to virtually evaluate different concepts in changing environmental conditions. The consideration of uncertain influences is an essential task within the development of a holistic simulation model. Some aspects (e.g. technical disturbances) can be...
In mechanized tunneling a significant loss of performance resulting from weak spots in the supply chain or unforeseen geological conditions is a frequent and costly problem. Furthermore, disturbances of critical machine components can have such impact on the production that unforeseen modifications become necessary. Due to the sequential character the malfunction of one element might evoke cascading-effects...
