摘　　要：将长距离水平定向钻探技术运用于岩土工程勘察,可有效弥补垂直钻探方式的不足,且其导向性能好,勘察精度较高。本文结合引江补汉工程输水隧洞岩土勘察工程,梳理出钻机、随钻测量设备、钻具等的使用情况,并提出钻进实施过程中的“取心钻进+定向钻进”交替进行的长距离水平复合定向钻进施工工艺方法,最后对实际施工过程中施工难点及应对措施进行介绍。Long distance horizontal directional drilling technology is applied to geotechnical engineering investigation.By using its advantages of traversing construction and trenchless,it can effectively make up for the shortcomings of vertical drilling method,and because of its good guiding performance,the investigation accuracy is high.Combined with the geotechnical exploration project of the water delivery tunnel of Yangtze‑replenish‑Han Project,this paper sorted out the use of drilling rig,measurement equipment while drilling,drilling tools,etc.,and proposed the construction technology method of“core drilling+directional drilling”alternating in the drilling implementation process,and finally introduced the construction difficulties and countermeasures in the actual construction process.
