二维高分辨自动地电阻率探测地下洞穴技术

TWO DIMENTION HIGH-RESOLUTION EARTH RESISTIVITY SURVEY FOR DETECTING UNDERGROURD CAVES

摘要: 高分辨地电阻率系统主要用于地下洞体(老窑采空、岩溶等人工或天然洞穴)探测。采用单极-偶极连续二维剖面观测,对采集的资料应用目标异常匹配滤波法或交汇法再现地下异常体形象.

Abstract: The high-resolution earth resistivity survey study mainly deals with detectal undergrourd caves, such as artifical caves or nature caves et al.. The pole-dipole electrode array is used in acquisition of the field data along the continuous two-dimention profile. The data are procssed by means of the target anomaly matched filtering technique and the across mapping method to show the underground anomalous resistivity bodies.
