摘　　要：随着我国特高压工程建设的发展,越来越多的线路走廊需途径高山或丘陵地区,机械化施工程度高的岩石锚杆基础应用比例正逐步提高。根据特高压工程荷载大以及岩石地基覆盖层厚的特点,结合理论研究与现场试验成果,提出了特高压工程岩石锚杆基础适用型式、破坏模式及其承载力计算、施工和质量检测等方面的建议,为特高压工程中岩石锚杆基础的推广与应用提供参考。With the development of UHV transmission line construction in China, the share of hilly-mountainous region has more percent in transmission line terrain. So, rock anchor foundation with the advantage of high degree of mechanization construction has been widely applied in UHV transmission line. According to the characteristics of UHV engineering： the large load and the thickness overburden of rock foundation, this paper proposed some suggestions for the foundation styles, failure mode, bearing capacity calculation, construction and quality inspection methods of rock anchor foundation in UHV engineering, based on the theoretical study and field tests, which could provide references for the popularization and application of rock anchor foundation in UHV engineering.
