Xingang Bridge located in Taizhou City of Zhejiang Province is a deck bowstring sunflower-shaped arch bridge. Taking this bridge as an example, the design characteristics of the sunflower-shaped arch bridge are systematically introduced. Through the overall design and structural analysis, the main parameters and structural form of the bridge are proposed, and the construction scheme is made according to the construction conditions. The model calculation shows that the bearing capacity and crack width of the bridge meet the current code requirements, which can provide the valuable reference for the construction of similar projects.
