摘　　要：老旧防空洞是一种隐埋于地下几米到几十米的人防设施,一般的仪器无法从地表对其准确定位。本文利用地球物理勘探微重力测量和瞬变电磁测量两种方法,分别对已知参数防空洞进行探测,通过和已知防空洞的参数进行对比,总结出了微重力探测老旧防空洞的有效方法。The old air defense shelter is a kind of civil air defense facility buried several meters to tens of meters underground.General instruments cannot locate it accurately from the surface.In this paper,two methods,microgravity survey and transient electromagnetic survey,are used to detect the known parameters of air-raid shelters.By comparing with the known parameters of air-raid shelters,an effective method of microgravity detection of old air-raid shelters is summarized.
