摘要
地质雷达应用于探测地下工程,常通过探测地下开挖区域间接地寻找目标。对因回填或坍塌空洞不明显的开挖区域,须通过研究开挖区边界以及地层缺失的雷达影像扰动特征,判定开挖区范围。现场探测实验表明,这种探测方法较准确,误差在允许范围内,达到了预期。同时,对干旱地区地质雷达探测地下埋藏物开挖区域的方法和影像特征进行分析和总结。
Geological radar is widely applied in detecting underground works, often indirectly by detecting the excavation area for the target. To detect the excavation area affected by backfills or collapses, it is necessary to study radar image disturbance features of excavation boundaries as well as stratum-missing places. The field experiment proves the method to be accurate, with allowable error, as expected. Meanwhile, the article analyzes and summarizes the methods and image features in detecting excavation areas with geological radar in arid areas.
