The borehole ultrasonic imaging method can precisely reflect the smoothness of the borehole wall , and then judge the weathering degree of the rock and determine thickness of the weathering bed
摘要钻孔超声成像方法能精确地反映井壁的光滑情况，进而判断岩石的风化发育程度，确定风化层的厚度。
Through some examples , we think that the ultrasonic imaging method that can obtain some parameters of the crack attitude and the opening is an effective method in studying the crack of underground rock stratum
经过多项工程实践，我们认为超声成像法对钻孔孔壁扫描获得裂隙产状、开度等参数是研究地下岩层裂隙的有效方法。
This paper introduces four kinds of mehtods that is used to investigate crack in underground rock stratum : borehole core method , ultrasonic imaging method , borehole television method , and borehole discharge well logging method
摘要本文介绍了地下岩层裂隙的4种勘察研究方法：钻孔岩芯法、超声成像法、钻孔电视法、钻孔流量测井法。
