摘要
介绍了声波层析成像技术(声波CT)的基本原理,并以某水电站大坝建基面下的防空洞探测为实例,利用声波层析成像技术反演确定了该部位的波速分布情况,根据波速分布划分出波速异常带,确定了防空洞的空间展布范围与规模,为后续处理方案提供了科学的依据。
This paper briefly introduces the basic principle of the acoustic tomography technique（Sound Wave CT）,taking the detection of Air-Raid Shelter under a hydropower station dam foundation surface as an example,the velocity distribution on-site were detected by using inversion of acoustic wave tomography technique.The wave velocity anomaly zone is classified according to the velocity distribution,and the space distribution and scale were also determined,which provides a scientific basis for the subsequent processing scheme.
