摘要
介绍了骊山北坡Ⅰ区坡体病害及整治试验工程中锚索钻孔的一些相关工艺技术，包括锚固工作平台搭设及钻机固定；钻孔工艺选择及机具装置研制；预防锚孔弯曲的措施；破碎带、裂缝带的钻进技术及封孔固壁堵漏技术。
The paper presents some relative techniques about anchor wire drilling hole of control test engineering of slope disaster in Area on north slope of Lishan. It concludes building working platform for anchor, fix of drilling machine, selection of drilling technology and development of drilling tools. The paper also presents measures for preventing drilling hole curve, drilling technique in broken zone and fissure zone and technique of sealing hole and pluging loophole.
