摘　　要：乌江索风营水电站Dr2危岩体加固施工作业面高差大、场地小、施工干扰大；危岩体岩层复杂，多条破碎带分布在山体中，必须穿越L1和L2裂隙。对索风营水电站Dr2危岩体距最低平台高差达110～134.5 m的上部锚索的特殊施工技术进行了介绍。Difficulties of large height difference of construction surface, small working site and complicated formations of dangerous rock exist in Suofengying hydropower station of Wujiang project with several fracture zones distributing in the mountain, the borehole must be drilled through fractures.The paper introduces the special construction technology used in upper anchor cable construction for Dr2 dangerous rocks in Suofengying hydropower station, where it has 110 ~134.5m height difference to the lowest platform.
