Abstract:
A method of assembling a wind-turbine tower which includes a plurality of tower sections including a lower section and an upper section to be connected to the lower section, includes: a step of measuring a diameter of an upper end portion of the lower section and a diameter of a lower end portion of the upper section; a step of applying a force in a radial direction of the wind-turbine tower to at least one of the upper end portion of the lower section or the lower end portion of the upper section so as to reduce a difference between the diameter of the upper end portion of the lower section and the diameter of the lower end portion of the upper section, on the basis of a measurement result of each of the diameter of the upper end portion of the lower section and the diameter of the lower end portion of the upper section; a step of suspending the upper section above the lower section while the lower section is disposed upright so that the upper end portion of the lower section and the lower end portion of the upper section face each other; and a step of connecting the lower end portion of the upper section and the upper end portion of the lower section.
