介绍了锚固技术在国内外的发展和应用状况，讨论分析了影响单根锚杆基础极限承载力的因素。指出了“送电线路基础设计技术规定”中单锚承载力计算存在的某些缺陷。提出了计算锚杆极限承载力的新方法，可供设计参考，并有待通过试验验证。
The development and application of anchorage technology at home and abroad are introduced. The factors affecting the ultimate bearing capacity of single anchor bolt foundation are discussed and analyzed. Pointed out that there are some defects in the calculation of the bearing capacity of the single anchor in the “Technical Regulations for Basic Design of Transmission Lines.” A new method for calculating the ultimate bearing capacity of the anchor rod is proposed, which can be used as a reference for design and needs to be verified by experiments.
