地震波CT技术主要用于二维空间探测，为查明某水电工程隧洞间围岩的溶蚀构造，布置多组交叉地震波CT探测剖面，利用二维地震波CT技术反演得到隧洞间围岩波速的空间分布，然后用专门的绘图软件绘制三维波速等值面并形成三维实体图形。根据三维实体图形中低波速围岩的空间分布，分析判断溶蚀构造的形态，从而实现对岩溶构造的精细化探测。

The seismic CT detecting technology is mainly used in two-dimensional space. To find out the Karst structure in the surrounding rock between the tunnels at a hydropower project, sets of crossing seismic CT detecting section were arranged and 2-d seismic CT technology was applied to detect the spatial distribution of wave velocity in the surrounding rock between the tunnels. Followed, a special drawing software rendering 3-d contour surface of wave velocity was adopted to form a 3-d materialized view. By analysis of the spatial distribution of low wave velocity, the Karst structure can be obtained.
