摘　　要：以炎陵至汝城高速公路曾家大桥4#、5#桥墩为例探讨了跨孔电磁波CT技术在岩溶地质异常探测种的应用情况。分析了电磁波CT探测技术工作原理、野外数据采集要点、数据分析处理流程,并对数据处理关键步骤进行了总结;通过对各探测剖面进行认真分析,编译出合理的剖面解释图并进行了正确解释,效果良好;获得了探测区内的岩土层对电磁波的吸收系数的准确认识,为电磁波CT探测提供了一种好的剖面分析和解释思路。In the case of Yanling to Rucheng Highway bridge 4#, 5# Pier,, this paper discusses the cross-hole electromagnetic wave CT technique and its application in karst geological anomaly detection. Moreover, we analyses the principle of electromagnetic wave CT detection method, on- field data collection soul, and data analysis flowchart, and summarizes the key steps in data processing. Through careful analysis of the probe profile, this article builds a reasonable explanation of the profile map and made a correct interpretation, and the result was verified. It gets an accurate understanding of the rock layer on the detection zone of electromagnetic waves, which provides a good section analysis and interpretation of CT detection of thinking.
