摘要： 利用Voxler三维可视化科学绘图平台，将地震波CT岩溶探测数据进行三维数据处理，建立地震波波速三维数值模型。对波速三维数值模型进行切片、体积渲染、表面渲染处理，分析和判断各岩土体的地震波波速范围，划分测区岩土分层和强岩溶发育区边界，建立场区岩溶强发育区的空间分布形态，提高地震波CT资料的空间解译准确性及有效性。

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
