Abstract
A method for lifting an asymmetric integral construction is provided, including the steps of determining proper lifting points on a construction to be lifted according to the position relationship between the construction and a base supporter, setting a dragging point on the bottom of the construction, the dragging point being located on the extension line of the connection between the gravity center of construction and the centroid of the lifting points, determining a projection point of the dragging point on the ground, arranging a dragging device between the dragging point and the projection point, installing a lifting system at a proper position, conducting lifting operation by means of the lifting system cooperated with the dragging device, and rectifying and fixing the construction after it is in place.
