摘要
在城市道路地下病害体检测中,探地雷达作为一种常用的物探方法,如果天线选择不合适,探测深度和分辨率往往达不到工程要求。该文从探地雷达天线类型、极化方向、中心频率及天线间距等方面,分析总结了在城市道路地下病害体检测中,探地雷达天线选择的主要技术要领,以期与读者共享。
In the detection of underground diseases of urban roads,the GPR is a common geophysical method.If the antenna is not selected properly,the detection depth and resolution often can not meet the engineering requirements.This paper analyzes and summarizes the main technical essentials of GPR antenna selection in the underground diseases detection of urban roads from the aspects of GPR antenna type,polarization direction,center frequency and antenna spacing,in order to share with the readers.
