Abstract:

Conghua Bridge is located in the middle of Conghua District of Guangzhou, and spans across Liuxi River from south to north. Its main bridge is a single-span through spatial arch-beam composite bridge. Its span is 136 m and its bridge width is 40 m. The elements of water and moon in "Liuxi Reflecting the Moon" are adopted in the bridge design, which let the arch rib take on the shape of the moon, and like a crescent rising on the banks of Liuxi River. Based on Conghua Bridge, the relative design contents of Conghua Bridge are introduced.
