Abstract: The seismic wave CT exploration results on the karst terrain investigation were processed by using Voxler digital threedimensional visualization platform. Some graphical processes such as slicing, volume and surface rendering were applied to the 3D numerical modeling of the seismic wave velocity. Throughout analyzing of the seismic wave velocities, the quality of rock mass in the surveyed field was characterized and boundaries with strong Karst development zones were developed. The spatial distributions of the karstic rock zones were also modeled so that the spatial interpretationsof seismic wave CT data were improved by the visualization software.

Key words: voxler, seismic wave CT, seismic wave velocity, 3D modeling
