摘要
在甘肃北山1号孔中使用钻孔雷达系统进行“单孔反射法”测量,首次获得深达500 m的钻孔雷达数据。采用频率100 MHz的天线在该孔中探测到22个岩石裂隙面,侧向探测半径达20m。北山1号孔钻孔雷达测试的实践表明:钻孔雷达测量是了解岩体内部裂隙延伸和岩体完整性的有效手段,对高放废物处置库场址评价有重要意义。
The borehole radar system has been used in Beishan borehole No. 1 （BS01） to do tne singlehole reflection surveey at a frequency of 100M Hz, and a lateral penetrating radius of 20 m has been reached. 22 fracture planes have been interpreted from the radar image with a depth of 500 m. Borehole radar survey proves to be an effective method to detect the fracture extension and rock integration of granite, and is of important significance in site characterization for high-level radioactive waste repository.
