摘　　要：在华北地区输电线路建设中最典型的岩石条件下,对单锚式和直锚式岩石锚杆基础进行试验,分析不同风化强度条件下岩石锚杆基础的破坏形态、锚杆与岩石地基的粘结力的增长过程和方式、影响岩石锚杆基础承载力的各种主要因素,并提出相应的建议,为华北地区输电线路岩石锚杆基础的应用提供依据。Based on the most common rock formations encountered in North China transmission line construction, experiments were conducted on single and vertical anchor - shaft foundations. Forms of foundation breaking under different weathering intensity, bonding forces between anchor - shaft and rock foundation, and major factors that impact foundation load bearing capability are analyzed. Recommendations are brought forward as the references to the application of rock anchor - shaft foundation in North China transmission line construction.
