Abstract

Techniques to investigate the soil with the help of different geophysical methods increased rapidly during the last decade. Nevertheless, the use of different geophysical methods results often in different interpretations of the investigated area. This paper deals with the joint interpretation of surface waves, refracted waves (full waveform) and resistivity data acquired in an urban area of old coal mining where cavities or zones of loosening are expected in the near subsurface. Special anomaly indices are determined for each geophysical method. A weighting process combined these indices to a “Joint-Anomaly-Indicator” for the whole investigated area. This results in a map which clearly shows those locations with a high probability of cavities or loosening.
