In the context of vigorously promoting the application of mechanized construction in mountainous areas of high-voltage transmission line engineering,this paper proposes a small pile anchor foundation suitable for mechanical hole formation of"half-rock and half-soil"foundation of mountainous transmission line engineering.At the same time,combined with the results of variable cross-section pile model test and numerical analysis,the bearing capacity design method of small pile anchor foundation was analyzed.In addition,the stiffness ratio formula of large and small piles is obtained by numerical fitting,and the uplift bearing capacity of the solution is partially safe under the condition of different pile diameter ratios.
