摘　　要：以构造钻孔实际资料为基础,对基岩隐伏区钻孔岩芯的构造形迹进行系统分析,阐述从单个钻孔岩芯判定断裂构造的地质依据,总结各类断层岩的宏观特征,并以此引伸压性、张性断层的辨别微象。其理论及实际资料基础较为可靠,对工程地质勘察及基岩钻孔地质编录具有一定的参考利用价值。On the basis of structure drilling material,drilling core′s structure features in concealed area are analyzed systematically.What′s more,it describes geological basis of identifying fault structure through single drilling core and summarizes the macro-characteristics of some kinds of fault rock,explicates the fine distinct of piezotropy and extensional fault.Its theoretical and practical material basis is reliable,which is significant to project geological survey and bedrock drilling geological logging.
