The invention relates to a method for realizing three-dimensional virtual simulation construction of a distribution line tower. The method comprises the following steps: grading and dividing a typical tower in a three-dimensional engine into units; splicing in the manner of connection point between the units or positioning by finely tuning in a rendering process; confirming an overall constructing manner of the tower, and then confirming the position and the orientation; and lastly, defining a linkage manner, confirming the overall orientation change and the linkage relation of the tower and realizing the automatic three-dimensional construction of the distribution line. According to the invention, the problem of time and space waste of the three-dimensional virtual simulation construction of the distribution line tower at present can be thoroughly solved; the three-dimensional simulation tower assembling of the distribution line is perfectly realized; a semi-automatic assembling method which is capable of displaying the maximum details and is efficient and accurate is supplied; a basis is further established for the required development.
