| Abstract: | Positioning for anchorage pipe of cable is one problem in construction of cable stayed bridge. This paper introduced the principle of 3 D analytical positioning method, in which positioning elements and precision are analyzed on the basis of geometric model of positioning objects. And then the precision of 3 D surveying based on polar method using total station instrument are studied systematically. This method has successfully proved in construction of several cable stayed bridge. |
