Seismic refraction tomography for geotechnical engineering and exploration.
The Rayfract® Seismic Refraction Tomography software allows reliable imaging of subsurface
velocity structure. Our tomographic data interpretation is based on physically meaningful
modeling of wave propagation with wave paths instead of conventional seismic rays. This
increases the numerical robustness of the inversion, especially in low coverage situations.
An initial 1D gradient model is determined automatically directly from the traveltime data, with
the Delta-t-V method (improved Herglotz-Wiechert method). This method delivers reliable
models even in case of velocity inversions. The initial model is then refined with true 2D WET
Wavepath Eikonal Traveltime tomography processing. Also, the software allows
interpretation of traveltimes with conventional Plus-Minus and Wavefront seismic refraction
