针对高频电磁波技术在北京勘察设计行业应用的空白,本次研究利用探地雷达技术对北京地区典型工程目标体进行了研究.针对不同的地下目标体对高频电磁波所反映出的不同反射特性,总结出一些图像特征规律.通过建立对各类雷达探测图像进行地质解释的理论依据和基础,本次研究对层状介质、地下管道、CFG桩、碎石夯扩桩、水泥土桩和洞穴等目标体的雷达图像特征进行了较系统的研究和总结,为今后日常的检测工作奠定了很好的基础.
Aiming at the blank about the application of high frequency electromagnetic wave on Beijing geotechnical exploration, the paper present a study that the GPR technology applies on typical targets in Beijing district. On the base of the different reflection characteristics given high frequency electromagnetic wave on typical targets, we summarize the imagine features. Through establishing the theoretical basis of geologic interpretation, the paper studies and summarizes the radar imagine feature of layer medium, underground conduit, CFG pile, debris tampered pile, cement and earth pile and burrow etc. The results show the well base of next daily detection works.
