摘要
孔内超声成像技术能提供工程勘察钻孔中岩层的三维影像资料。以2AC51KSZ-7钻孔为例,介绍了孔内超声成像技术在铁路工程勘察中应用的几个方面,结果表明:孔内超声成像技术在孔内裂隙的探测上优于综合测井技术,裂隙的方位角倾角信息等可为地应力方向测量提供数据支撑,对铁路设计具有较大的意义。
Intra—hole ultrasound imaging technology can provide 3D imaging data for rock formations in engineering survey drilling.Taking 2AC51KSZ-7 drilling as an example,this paper introduces several aspects of the application of intra-hole ultrasonic imaging technology to the railway engineering survey,and the results show that intra-hole ultrasound imaging technology is superior to comprehensive logging technology in the detection of intra-hole fractures,and the azimuth inclination information of the fissure can provide data support as the geostress direction measurement,which is of great significance to railway design.
