- Abstract: In the course of the preliminary planning of the new Gelnhausen–Fulda railway line which is part of the railway project Hanau–Würzburg/Fulda, two route options with tunnels, bridges, cuts and embankments are to be investigated and assessed as efficiently as possible with regard to potential geotechnical risk areas. Due to the geological and hydrogeological conditions within the north‐eastern Hessian Buntsandsteingebirge, several groundwater levels, landslides in tunnel portal areas and karstification structures are to be expected on the two route options, each of which is approx. 45 km long. In order to obtain detailed and, above all, large‐scale knowledge of geotechnical hazards of each route = in the preliminary stage of the exploration programme, geophysical surface investigations are a cost‐ and time‐optimized exploration method in addition to standard drilling. These findings as well as existing subsurface information are combined by means of BIM, so that risk areas can be identified at an early stage of the project and taken into account when selecting the most affordable route.

Abstract: Im Zuge der Vorplanung der DB‐Neubaustrecke Gelnhausen–Fulda als Teilmaßnahme des Projekts Hanau–Würzburg/Fulda sollen zwei Trassenvarianten mit Tunneln, Brücken, Einschnitten sowie Dämmen untersucht und möglichst effizient hinsichtlich potenzieller geotechnischer Risikobereiche abgeschätzt werden. Aufgrund der geologischen und hydrogeologischen Gegebenheiten innerhalb des nordosthessischen Buntsandsteingebirges ist auf den beiden zu untersuchenden jeweils ca. 45 km langen Trassen mit etlichen Grundwasserstockwerken, Rutschungen in Portalbereichen und Verkarstungsstrukturen zu rechnen. Um bereits in der Vorstufe des Erkundungsprogramms detaillierte und vor allem großräumige Erkenntnisse über die geotechnischen Gefährdungsbilder der einzelnen Trassen zu erhalten, bieten sich zusätzlich zu einem punktuellen Bohrprogramm oberflächengeophysikalische Untersuchungen Erkundungen an. Diese Erkenntnisse sowie geologische und hydrogeoglogische Bestandsunterlagen werden in einem BIM‐Gesamtmodell eingebunden, sodass Risikobereiche möglichst frühzeitig erkannt und bei der Trassenoptimierung berücksichtigt werden können. … (more)
