岩芯定向技术是一项能借助钻探手段。从孔内取出定向岩芯,并进而计算出钻孔穿越岩体的各种结构面产状数据的新技术,此项技术可广泛用于工程岩体研究;水电、石油及固体矿产的地质构造分析;海洋地质调查及古地磁研究等。 本文介绍了作者研制的两种定向钻具和仪器。分别可用于完整及较破碎地层。文中介绍了钻具的原理、结构及从1984年起在工程岩体研究中的应用情况。最后根据几年来的施工经验、对几个技术问题进行了探讨。
Core orientation technology is one that can be drilled. The removal of the directional core from the hole and the subsequent calculation of the new technology for the production data of various structural planes passing through the rock mass can be widely used in the study of engineering rock mass. The geological structure of hydropower, petroleum and solid mineral Analysis; Marine Geological Survey and paleomagnetic research. This article describes two kinds of directional drilling tools and instruments developed by the author. Available for complete and more broken formations respectively. This paper introduces the principle, structure of drilling tools and their application in engineering rock mass research since 1984. Finally, according to several years of construction experience, several technical issues were discussed.
