The round tower anchor plate adopts the structure form of multi-level steps to disperse the anchorage force and improve the bearing capacity of the anchor plate. This paper takes OVM.M15-9D and OVM.M15-12D anchor plates as examples, by changing their structural forms, that is, removing the end two steps, using ANSYS finite element analysis and load transfer test methods, to compare and study their effects on the bearing capacity of anchor plates, and analyze the force transfer forms of multi-step steps under the anchor concrete.
