防空洞探测属于地下洞体探测中的一种特殊工程地质问题。选用小线框瞬变电磁法应用于地下空洞的探测,对于施工区地表有较强的适应能力,工作效率较高。其数据处理解释采用全期定义将实测瞬变衰减曲线转换为视电阻率深度曲线,根据地下空洞的瞬变电磁响应特征分析等视电阻率曲线的形态来确定空洞体存在,证明了在城区建筑基坑中采用小线框瞬变电磁法在探测地下空洞中的有效性。
Air defense detection belongs to a kind of special engineering geological problems in the underground cavity exploration. Use of small wireframe transient electromagnetic method applied to the detection of underground cavities, the construction area of the surface has a strong adaptability, higher work efficiency. The data processing and interpretation of the full definition of the measured transient decay curve is converted to apparent resistivity depth curve, according to underground transient electromagnetic response characteristics of apparent resistivity curve shape to determine the existence of hollow body, proving that in urban buildings The Effectiveness of Using Small Wireframe Transient Electromagnetic Method in Detecting Underground Cavity in Foundation Pit.
