摘要:

北运河香河段的河道蜿蜒形态，恰似一件寓意吉祥美好的如意，串联着整座香河新城。如意香河大桥主桥设计以“如意”为设计立意，进行了极具地域特色的景观桥型设计。主桥采用三跨抱翅型拱梁组合体系，全长256 m，跨径布置为56.5 m+164.5 m+35 m。主桥外观新颖独特、富有韵律、与结构受力融合一体，去繁就简、舒展大方，标志效应显著，可为类似的景观桥项目设计提供借鉴。主要介绍了该桥的方案设计、总体布置、结构设计、景观设计、BIM应用等内容。

Abstract:

The river winding shape of the North Canal in Xianghe is like a auspicious and beautiful Ruyi, which connects the whole Xianghe New Town. The main bridge design of Ruyi Xianghe Bridge is based on the design concept of 'Ruyi', and the landscape bridge design with regional characteristics is carried out. The main bridge adopts a three-span wing-holding arch-beam composite system, with a total length of 256 m and a span arrangement of (56.5+164.5+35) m. The main bridge has a novel and unique appearance, full of rhythms, and is integrated with the structural performance. It is simple and generous,the sign effect is significant. It can provide reference for the design of similar landscape bridge projects. This paper mainly introduces the scheme design, overall layout, structural design, landscape design and BIM application of the bridge.
