探地雷达在调查地下人工构(建)筑物中的应用

运用探地雷达对武汉市汉阳区月湖一建筑场地下人工混凝土基础以及青山区某公寓建筑场地地下人防工程进行探测定位。通过工程实例,从探测原理、技术方法、成果分析等方面,介绍了在城市工程建设中探地雷达在调查地下人工构(建)筑物中的成功应用。对探地雷达剖面的处理分析,圈定了测区内多块建筑场地地下混凝土结构的平面分布范围,为建设工程的地基处理设计和桩基施工定位提供重要资料;探地雷达剖面不仅能精确显示人防工程的平面边界位置,而且还能反映人防工程的内部结构特点。

Application of GPR in the Detection of Underground Artificial Constructions

GPR was applied in the detection and location of underground artificial concrete base at Hanyang Yuehu and civil air defense at a building site of Qingshan in Wuhan city.Combined with engineering instance,the applications of ground penetrating radar in city reconstruction were introduced in terms of its principle,technique and method,and results.On the one hand,the processed GPR profiles can be used to delineate the underground artificial concrete base of building fields and provides important data for the plan of groundsill processing and location of pipe piles;on the other hand,they can not only display the boundaries of the civil air defense accurately,but also reflect its internal structural characters.
