富阳公望大桥设计与创新

Design and Innovation of Fuyang Gongwang Bridge

摘要:

富阳公望大桥是一座融合现代美学与工程技术的梁拱组合桥。其主桥采用35 m+2×95 m+35 m宽幅钢箱梁-蝴蝶形钢叠拱组合体系，不仅赋予了桥梁独特的外观，同时也确保了结构的合理受力。通过新型偏态曲线钢叠拱的设计，不仅丰富了桥梁的视觉效果，还增大了桥梁的整体刚度和稳定性；此外，大桥的设计与施工过程中还运用了BIM技术，大大提高了工程建设效率和精度，并实现了复杂曲线钢拱桥的快速工业化建造。大桥的设计巧妙地结合了空间构成的形式美与结构受力的功能性，使其成为北支江上的一个标志性建筑，为城市景观拱桥的设计提供了新的思路和参考。

Abstract:

The Fuyang Gongwang Bridge is a girder-arch composite bridge integrating modern aesthetics and engineering technology. Its main bridge is a (35 m+2×95 m+35 m)-wide steel box girder-butterfly steel-arch composite system, which not only endows a distinctive appearance of bridge, but also ensures a rational stress of structure. Through the new skew curved steel-arch composite design, not only the visual effect of the bridge is enriched, but also the integral rigidity and stability of the bridge are enhanced. Furthermore, BIM technology is employed in the design and construction process of the bridge, which significantly increases the engineering efficiency and precision, and realizes the rapid industrialized construction of complex curved steel arch bridges. The design of the bridge cleverly combines the formal beauty of spatial composition with the functionality of structural stress to make it become a landmark building on the Beizhi River, which provides the new insights and reference for the design of urban landscape arch bridges.
