岩溶探测中的弹性波CT方法

The application of elastic CT method in karst prospecting

弹性波CT方法,又称地震波层析成像技术。这种技术利用大量的地震波速度信息进行专门的反演计算,得到测区内岩土体弹性波速度的分布规律。利用这种方法探查岩溶的分布、形态及连通性与其它测试方法比较,分辨率高、效率高、空间位置准确。在岩溶发育地区进行工程勘察,采用常规钻探与弹性波CT成像相结合的勘察方法,可消除工程安全隐患。

Elastic CT method is known as seismic CT. It computes the distribution of velocity in the rock and soil body using speed information of seismic wave by special methods. Elastic wave CT can be used to detect the formation and the distribution of karst. It is more efficient and accurate than other conventional exploration methods. The combined application of drilling and elastic wave CT method may eliminate the probability of potential disaster during engineering survey in karst region.
