A numerical research method was adopted to study the force transfer mechanism and internal force distribu-tion of rock bolt foundation under uplift load.The stress process of rock bolt foundation under uplift load was analyzed,the axial force of reinforcement bar,concrete and rock was compared,and further the values of bolt diameter,bolt length,anchor solid diameter and rock mechanical parameters were changed.The variation of bearing capacity of rock anchor foundation was analyzed.Through the research,the basis and reference were provided for the design and application of rock anchor foundation in the power transmission line tower foundation in the strongly weathered rock area.
