宜兴市陶都路景观绿桥设计

Design of Taodu Road Landscape Green Bridge in Yixing City

摘要:

针对宜兴市陶都路建设导致的龙背山东西向割裂问题，通过工程技术措施之一的景观绿桥加以修复，重构山体脉络，恢复其生态功能。创新性地采用“装配式简支板梁结构+空间装饰桁架”组合体系构建绿桥：通过简支板梁形成结构骨架；通过三维曲面装饰桁架实现桥梁外形；通过桥面绿化恢复山体走势。项目实现了快速化施工，既缩短了工期，又节约了工程造价。项目建成后成功地串联了山体，实现了生态修复的目的，取得了良好的经济和社会效益，为类似的城市生态修复工程提供了可借鉴和参考的案例。

Abstract:

To address the east-west fragmentation of Longbei Mountain caused by the construction of Taodu Road in Yixing City, as an engineering technical measure, the repair of a landscape green bridge is to reconstruct the mountain network and restore its ecological functions. The composite system of "fabricated simple-supported slab girder structure + spatial decorative truss" is innovatively used to construct the green bridge. The simple-supported slab girder is used to form the structural framework. The three-dimensional curved decorative truss is used to realize the appearance of the bridge. And the bridge deck greening restore the trend of the mountain. This project can realize the rapid construction, which not only shortens the construction period, but also saves the engineering cost. The completed project successfully connects the mountains, achieves the goal of ecological restoration, and gains the good economic and social benefits, which provides a replicable and referring case for similar urban ecological restoration projects.
