Abstract
With the purpose of providing a detailed sedimentary geological model, as basis for improving groundwater pumping, a SH-wave reflection seismic survey was performed along a railway ramp of the great belt tunnel in Denmark. The survey provided a high resolution image of the very shallow subsurface and the SH reflection result was the primary source for the geological interpretations. Refraction seismic analysis of P-wave reflection records, surface wave measurements and VSP measurements in two boreholes were also carried out. Together with the SH reflection result and available borehole data these results were used to create a detailed geological model.
