岩溶地质灾害勘察中井间地震波CT技术的应用

Application of Crosshole Seismic Wave Tomography in Karst Geological Hazard Exploration

该文结合唐山市体育场岩溶地质灾害勘察的工程实例,应用井间地震波CT方法来研究钻孔之间的地质剖面。该技术在划分岩溶或地质异常体的空间位置等方面,以速度标识图像表明地质体介质内部结构和特性,是一种高分辨率、数字化的测试技术方法。

Crosshole seismic wave tomography is used to research geologie section betwe en drill-holes in the palaestra, Tangshan city. Th i s paper introduced the application of crosshole seismic tomography technique in karst geological hazard exploration.With image of velocity identifi cati on to indicate construction and characteristics of geologic body,it is a bet te r method for high resolution and digitization in detecting the position of anom alous geologic body and so on.
