城市景观斜跨双曲空间钢拱桥总体设计

Overall Design of Urban Landscape Oblique-span Double-curve Spatial Steel Arch Bridge

摘要:

随着社会的发展，城市桥梁的景观作用在桥梁设计中越发受到重视，桥梁景观愈加主导结构设计，进而提高了桥梁结构设计的要求。位于环坝路的葵坝路景观跨线桥作为深圳国际生物谷坝光核心启动区的标志性建筑之一，桥梁景观设计上须在保证优美的前提下着重体现桥梁的原创性、独特性。为配合桥梁景观设计效果，桥梁结构采用斜跨双曲空间钢拱桥，结构上具有独创性。对桥梁方案、桥梁拱轴线、变截面拱肋、弯斜钢梁等关键节点设计内容进行了论述，为复杂结构的城市景观桥梁设计提供参考。

Abstract:

With the development of society, the landscape role of urban bridges has become increasingly important in bridge design, and the bridge landscapes have increasingly dominated the structural design, thereby raising the requirements for bridge structural design. The Kuiba Road Landscape Overpass located on Huanba Road is one of the landmark buildings in the core startup area of the Shenzhen International Biovalley. The bridge landscape design needs to emphasize the originality and uniqueness of the bridge while ensuring its beauty. To match the bridge landscape design effect, the oblique-span double-curve spatial steel arch bridge is used as the bridge structure, which is structurally original. The design contents of the key elements such as bridge schemes, bridge arch axes, variable cross-section arch ribs and curved inclined steel beams are discussed, which provides the reference for the design of urban landscape bridges with complex structures.
