- 摘要:
- 超声波测井是一种以研究地下介质体的声学特性为基础的地球物理勘探方法,依据声波在地下介质体中传播的速度来评价介质体的完整性。文章在阐述超声波测井原理的基础上,介绍了该方法在川东北—川西输气联络线工程隧道地质勘察中的应用及效果,它能够有效地确定隧道围岩的岩体完整性。
Ultrasonic logging technique is a kind of geophysical prospecting methods based on the study of underground medium acoustic characteristics. The integrality of underground medium can be evaluated by analyzing the acoustic wave velocity while propagating in the medium. Based on the principle explanation of ultrasonic logging technique, this paper introduces the application and efficiency during the pipe-tunnel survey in the Tieline Project from Northeastern Sichuan to Western Sichuan. This method can determine the rock mass integrity of the wall rock surrounding tunnel.2009,s1(s1): 41-43 收稿日期:2009-3-6分类号:U45 U452.1作者简介:徐帅陵(1976-),男,山东东营人,工程师,毕业于中国矿业大学,参加工作后先后从事安平—济南天然气管道、鲁皖成品油管道、川气东送管道等工程施工。
