摘　　要：钻孔电磁波CT是一项利用电磁波吸收原理进行探测的技术，本文探讨了电磁波CT技术在桩基础岩溶探测上的应用情况，包括反演算法的选取、现场测试注意的问题、桩基础对测试的影响等等，最后通过在桩基础岩溶探测上的实际应用，说明电磁波CT技术在桩基础岩溶探测上具有较好的效果。Borehole electromagnetic CT is a detecting technology using electromagnetic wave absorption principle. This paper discusses the electromagnetic CT technology applying to detect karst in Pile foundation, including inversion algorithm selection, attention of field testing, the impact of pile foundation itself on the test ,ect. At last, through the practical application on karst detecting in Pile foundation, make out that electromagnetic wave CT technology have good results in detection karst in Pile foundation.
