Abstract:Three bridges spanning Loujiang River are simultaneously designed on Xinghan Street, Lujing Road and Huachi Street in Suzhou Industrial Park. Under the premise of prioritizing functionality, the landscape design of the bridges not only takes into account the overall situation, but also highlights the individual characteristics of each. Based on the positioning of the park and the regional cultural features of Suzhou, the three types of the bridges are conceptualized around the themes of “Music”, “Melody” and “Dance”. The Xinghan Street Bridge is designed as a 76-m span bowstring arch bridge. The dual arch ribs are on its north side that converge at the arch crown to a single arch rib on the south side, which creates a unique and dynamic form. The Lujing Road Bridge is a steel arch bridge with an 87-m span, but the two arch ribs are in an open shape, and its sidewalk winds outward along a smooth S-curve from the beam end to the middle span, making the bridge shape more vivid. The Huachi Street Bridge is designed as a three-span (83+28+28.5-m) cable-stayed bridge. The high and low pylon columns of its V-shaped main pylon present a dynamic and dancing beauty, and its cables present a continuous beauty of tension from the river span through the main pylon to the bank span. In terms of structural design, three-dimensional refined design is adopted to ensure the design precision of spatial irregular structures. Taking into account safety, economy and artistry, the optimal scheme is proposed.
