Abstract
The new high-speed railway line from Nuremberg to Ingolstadt consists of numerous structures, including nine tunnels. In this issue of FELSBAU, several contributions focus on the engineering geology as well as on geotechnical aspects of these structures. The present contribution is supposed to give a brief introduction to the historical and regional geology of the complete project site and to highlight some of the classical engineering geological problems of ground modelling in this specific area. The new railway line crosses more or less flat lying formations of Mesozoic to Cenozoic sedimentary rocks that form the scarped table-land of Bavaria. The thick strata sequence comprises different lithostratigraphic units, that originated in a variety of sedimentary settings. Due to paleoenvironmental and climatic conditions, tectonic processes and other parameters, sedimentary rocks of different facies, fabrics and composition have been formed. Even times of non-deposition strongly influenced the physical condition of the preserved rock sequences by processes like weathering, karstification or erosion. Precise and detailed knowledge of these complex geological processes is the only key for understanding the interrelationship of earth history on the one hand and underground conditions which we encounter today on the other. This is the precondition for accurate underground models.
