| Abstract: | The right-branching bridge in Jiangxin Island of Nanjing Yangtze River Tunnel is a self-anchored suspension bridge with single tower and its main tower＇ s outer outline is a variable cross-section surrounded by multi-segment concave arc, convex arc and transitional arc. And the curvature degree of cross-sectional arc shows in a continuous irregular change when the height of tower changes. This construction has a high precision requirement. From the aspects of measuring instruments configuration, measurement system settings, vertical degree control of the single tower, the single tower construction measurement and control technology was introduced. |
