摘　　要：分析了目前岩石锚杆基础在勘察、设计、施工与检测等方面的工程应用现状,提出了相应的解决对策与技术措施。通过采用高强度钢、涨壳式锚杆等新材料、新工艺,以及采用锚孔扩底基础、复合式基础、锚筋群桩基础等新型基础型式来扩大岩石锚杆基础的应用范围,为其更广泛地应用于输电线路工程提供参考。The rock anchor foundation applications for transmission line in investigation, design, construction and detection were studied. Some technical measures were proposed, such as using high intensity steels and swelled rock anchor. And the hole bottom expanding foundation, the composite foundation and group steels foundation could enlarge the application scope of rock anchor foundation in transmission line, which could provide references for other engineering applications of rock anchor foundation
