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。 Based on the engineering example of karst geohazard investigation in Tangshan Stadium, this paper studies the geological profile between boreholes using the crosswell seismic wave CT method. The technique is a high-resolution, digitized test technique for identifying the internal structure and characteristics of geologic media by identifying the velocity with the help of identifying the spatial location of karst or anomalous bodies.
