【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。更多还原

【Abstract】 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 the absorption coefficient of electromagnetic waves,which provides a good section analysis and interpretation of CT detection of thinking.更多还原
