当用于供水或供气的地下管道被埋在地下时,可能会遇到一些障碍物,例如未知的管道或石头。为了避免这种情况,需要从地面检查地下条件。对于这样的检查,使用超浅层反射法。我们使用一个巨磁致伸缩振动器作为震源。在这项研究中,首先,P波的方向性的巨磁致伸缩振动器澄清。其次,进行了埋地混凝土试块的检测实验。在本实验中,互相关分析被应用。然而,从混凝土块反射的波的到达时间没有被确认。从巨磁致伸缩振子的P波方向性出发,分析了其产生的原因。为了获得较好的效果,提出了放大互相关分析方法。通过这种分析,可以高精度地估计混凝土块的埋置深度。
When underground piping for a water supply or gas supply is buried, some obstacles such as unknown pipes or stones can be encountered. To avoid such situations, an examination of the underground condition from the ground surface is needed. For such an examination, the ultra-shallow reflection method is used. We use a giant-magnetostriction vibrator as the seismic source. In this study, first, the P-wave directivity of the giant-magnetostriction vibrator is clarified. Second, the experiment of detecting a buried concrete block is conducted. In this experiment, the cross-correlation analysis is applied. However, the arrival time of the wave reflected from the concrete block is not confirmed. On the basis of the P-wave directivity of the giant-magnetostriction vibrator, the causes are assumed. To obtain good results, the magnified cross-correlation analysis is proposed. By this analysis, the depth at which the concrete block is buried can be estimated with high accuracy.
