Für mehr Tempo bei der dringenden Brückenmodernisierung im deutschen Straßen‐ und Schienennetz ist es erforderlich, auch die Bautechnik für Brücken zu modernisieren. Die neuen Brücken sollen möglichst schnell gebaut werden können und schön, nachhaltig und robust sein. Es zeigt sich, dass Fertigteilbauweisen für dieses Anforderungsprofil besonders vorteilhaft sein können. Die Chancen, die diese Bauweise...
Tunnels in unfavorable ground conditions are exposed to high internal stresses due to localized loading at the outer face. Addition of extra layers of compressible material as a countermeasure needs more material and greater excavation volumes which is in conflict to the global goals of CO2 reduction. Thus, two alternative types of segments with higher bearing capacities are proposed that allow for...
