| Abstract: | Combining with construction surveying of Xintongyang Canal extra large bridge in Taizhou City, this pater intro- duces the positioning methods for cable anchor tube of tower and precasting main girder of a cable-stayed bridge with single tower and single cable plane. Through calculation and derivation for three-dimensional corrdinate of cable anchor tube, it＇s three-dimensional equation is established, positioning device for construction tube is developped, so the positioning and loft- ing precision are ensured. |
