探地雷达在穿路顶管及路基扰动检测中的应用

Application of Ground Penetrating Radar in Pipe Jacking Across Highway and Subgrade Disturbance Detection

探地雷达技术具有整体性、连续性、直观性、快速性、简便性等特点,高速公路的道路结构分层和金属管道性质及其电磁参数差异为探地雷达检测提供了基本物理前提。通过浙江一天然气管道顶管穿越高速公路段的探测实例表明,探地雷达技术可有效地用于顶管穿越高速公路时的顶管及其对路基土体扰动异常范围的检测。

Ground penetrating radar technology has the advantages of integrity, continuity, intuitiveness, rapidity and simplicity. Highway structure classification and metal pipe properties as well as electromagnetic parameters difference provide the basic physical premise for around Denetratina radar detection. Through a detection example of natural gas pipeline across highway in Zhejiang, it is indicated that ground penetrating radar technology can be effectively used to detect pipe jacking across highway and the abnormal range of subgrade soil disturbance.
