摘要
主要介绍了新一代超声波钻孔电视的主要组成部分及其性能特点,并初步比较了其与常见的光学钻孔电视和前几代超声波钻孔电视的区别。通过在某隧道工程区勘察工程中的应用研究,说明新一代超声波钻孔电视可以提供大量有效可视的钻孔岩体定量数据,为工程设计的定量化分析提供了详细的数据资料,为提升现有的工程勘察技术水平提供了一条有效的技术途径。
This paper mainly deals with the components of new acoustic borehole televiewer and the performance characteristics; at the same time, the paper compare the new acoustic borehole televiewer with the ordinary optical one and the old acoustic one. The application case into a geotechnical investigation of a tunneling project shows that the new acoustic borehole televiewer can give large quantities of effective and apparent data rock mass around borehole, and these data are very good basis for the quantitative analysis of engineering design and point out one effective access to improve the technological level of geotechnical investigation.
