Abstract

Geophysical methods are able to fill the gap between boreholes and to provide a measure of the spatial continuity of structures. Borehole seismic tomography promises the highest resolution when applied at a local scale of a few tens of meters. Currently, almost exclusively P-wave tomography is employed in geotechnical oriented tomographic surveys. However, from the geotechnical perspective, the benefit of P-wave tomography is rather limited. It is the S-wave structure of the ground which is crucial to derive geotechnical relevant parameters, such as shear strength or other elastic moduli. Up to now, only little effort has been made to develop the borehole S-wave crosshole tomographic method. S-wave tomography has some clear advantages compared to conventional P-wave tomography, such as a better spatial resolution and a higher sensitivity to material changes. Furthermore, S-waves are only slightly influenced by the ground water table and S-waves passing this zone are not much affected by ray bending compared to P-waves. Within this paper we present first results of a newly developed S-wave tomography system and field results from different test sites.
