The invention provides a simulation checking method for anti-overturning capability of an overhead distribution line electric pole, and belongs to the field of electric pole stability checking.The method comprises the steps that firstly, geometric dimensions of an electric pole and a foundation computational domain are determined, and a geometric entity model of the electric pole and the foundation is established based on ANSYS software; secondly, determining a grid type and a grid size, establishing an electric pole and foundation numerical value grid model, and importing the model into FLAC3D software; then, selecting a proper constitutive model and a yield criterion, determining physical and mechanical parameters of the electric pole and a foundation rock-soil body, and setting initial conditions and boundary conditions of calculation; and finally, in combination with an external load condition, completing simulation solution of the model based on FLAC3D software, and in combination with a solution result, judging whether the electric pole of the overhead distribution line overturns or not. The method is low in cost, short in time consumption and high in repeatability, can directly observe the deformation and damage process of the rock-soil body, can effectively simulate the actual process of anti-overturning checking of the electric pole, provides a basis for prevention and treatment of electric pole overturning, and improves the extreme weather handling capacity of an urban and rural power distribution network.
