High resolution hybrid seismic investigation mapping the weathering layer thickness and for estimating the bedrock quality in the area of a new planned nuclear power station; 7 hybrid seismic profiles totalling 6.1 km, depth of investigation: 300 m. Up-hole shots in 8 boreholes down to 200 m. Down-hole shots in 3 borholes down to 70 m to determine p- and s-wave-velocity to derive the poisson’s ratio. Multichannel analysis of surface waves (MASW) to determine the shear-wave velocity field; 1 test profile of 300 m length.
