摘　　要：锚杆基础具有"资源节约、环境友好"的特点,在特高压直流线路工程中已逐渐从试用迈入推广应用的阶段。对±800kV向上线、锦苏线、糯扎渡送电广东等特高压直流工程中应用锚杆基础的技术和经济效益展开较详尽的数据分析,结合已有成果关于锚杆基础的应用实践提几点建议(包括锚固长度、粘结强度参数、水平承载力等),可供后续同类工程参考和借鉴。Rock anchor foundation with the gradually been experiencing the stage from the advantage of resource conservation and friendly-environment, has introduction to widely application phase. In this paper, The economic and social benefit of rock anchor foundation is present by detail data analysis in the projects of _ 800kV XiangJiaBa- ShangHai, ±800kV JingPing-SuNan and _800kV NuoZhaDu Ultra-High Voltage Direct Current （UHV-DC） transmission line. Meanwhile, the design theory and research results of anchor foundation have been summarized. Lastly, some discussion work and suggestion on the application of rock anchor foundation are put forward, including the proposed values of anchorage depth, Bond strength and the lateral bearing capacity.
