Rational and efficient ground investigations for industrialised construction of new railways

It is becoming increasingly clear that a fundamentally changed way of working must be introduced, with a more rational and industrialized construction process, in order to be able to transfer more transport work to climate-friendly railway quickly enough. This project aims to contribute to such a process by developing and testing a methodology for rational soil surveys that allows for a faster, easier and cheaper way to produce a land forecast for environmental testing, cost calculation and risk assessment. The methodology will be tested on representative parts of the section Hässleholm - Lund. The first step in the process is the integration of relevant existing data in a geo-database with appropriate visualization tools. Based on the early geomodel, a possible trace line is established, and soil surveys are planned. The geomodel is also the basis for an archaeological terrain analysis with methods for early identification of probable places / areas with cultural relics. The ground surveys begin with drone-borne geophysical surveys, which form the basis for planning detailed investigations with ground-based geophysics and geotechnics. The results are entered in the geodatabase and analyzed afterwards. Integrated modeling of different types of data will be implemented to provide better spatial information on material parameters as well as the estimates of these. Methodology and algorithms for automated determination of forecast for foundation class with uncertainty factor / risk level will be developed with an gradual updating of expected basic conditions based on data available at the current stage.
