声波穿透层析成象技术及其工程应用

Sonic Computerized Tomography Technique and Its Application to Rock Engineering

本文提供长科院在声波穿透层析成象反演波速场研究方面取得的一些成果。通过清江隔河岩、宣恩龙洞及新安江电站三个工程应用实例,介绍了层析成象技术的方法应用。对所采用的反演算法优点及局限进行了讨论,对今后深入开展层析成象技术的研究前景作出了展望。

In these years the wide application of sonic detecting technique to rock engineering and the development of the caculating techniques processing sonic transmision information by using computer to develop computerized tomography technique (CT) to solve sonic velocity field have become the newest subject of the study of rock sonic detecting technique.In this paper, some sonic velosity field results inverted by using CT are given. By the use on three projects, i. e. Genevan, Longdong and xin' anjiang, the method of the application of the CT is introduced. In the paper the superiorities and the limitations of the invert algorithm are also discussed. The vistas for further development of CT are shown.
