The invention relates to a tower material location method for a power transmission tower spatial model. The method comprises the steps of establishing a tower material section of a power transmission tower in a local coordinate system; selecting a location vector according to an actual placing direction of a tower material of the power transmission tower; and locating the tower material of the power transmission tower in a global coordinate system according to the tower material section, the location vector and a vector location method. According to the technical scheme provided by the method, the tower material location problem of a power transmission tower structure is solved.
