Abstract

Seismic refraction imaging is a technique that has seen an increase of applications in engineering during recent years. In the work presented here a case of refraction tomography in the city of Copenhagen is discussed. The survey included two modalities; 1. a surface survey where 13.9 kilometers of crooked lines along segments of the planned underground metro were mapped, 2. borehole “walk-away” seismic refraction surveys in twenty nine boreholes located in proximity to the surface lines. The overall aim was to map the extension of the near-surface unconsolidated sediments and their interface with underlying sequences of limestone. The results showed it was possible to map the unconsolidated sediments and the underlying limestone. This led to a more reliable interpretation of the surface results along the sections where neither geology nor borehole data was available.
