The invention relates to a method for testing basic overturning resistance of a fire wire conical electric pole under the action of a wind load. The method comprises the following steps: firstly obtaining dynamic wind speed value at specific wind grade based on a harmonic synthesis method and Davenport spectrum, then respectively calculating equivalent moment of the wind load distributed on a conical electric pole and a wire on ground to obtain equivalent total moment, then determining equivalent force of a loading point according to height value of an electric pole equivalent force loading point from the ground, and finally carrying out overturning resistance test. The invention also provides a device for testing the basic overturning resistance of the fire wire conical electric pole under the action of the wind load. The method provided by the invention has the advantages that a single-point equivalent force applying process is adopted for testing the basic overturning resistance of the fire wire conical electric pole under the action of a certain wind speed, operation is simple, less time is consumed, cost is low and simulation is accurate.
