摘要
结合公路工程实例,对电场波CT探测技术进行简要说明,分别通过Surfer和Voxler软件作出电磁波CT二维与三维吸收系数图像,并进行对比研究。研究结果表明:二维图像可以直观反映两孔间地下介质的构造形态;三维图像内容更为丰富,可以取得各深度范围的电磁波吸收系数切片,重现空间内地下介质的构造形态,为工程地质勘察提供更详尽的资料。
This paper have introduced the application of the electromagnetic wave CT method in highway engineering. And the contrast reaserch about the electromagneitc wave absorption cofficient CT 2D and 3D image have been made. The results show that the 2D image can reflect the undergound structure between two drillings, and 3D image contains more information, such as the electromagneric wave absorption coefficient section of different depths. The 3D image can reproduce the structures of underground medium and provide more detailed information for engineering geological exploration.
