兴旺大桥为（29．25m ＋76．5m ＋29．25m）中承式系杆拱桥，拱肋外倾24°，边腿与主拱脚形成 V 撑。为减小温度效应对拱梁固结处及基础的不利影响，在主跨设2道伸缩缝，同时设置系杆以平衡拱的水平推力。通过兴旺大桥主桥的总体设计介绍，为同等跨径的特色景观桥梁设计提供一种选型参考。

Xingwang Bridge is a 29.25 +76.5 +29.25m half-through tied-arch bridge with a 24°arch-rib camber and a chevron brace between its side pier and main arch springing.In order to decrease the adverse effects to the foundation and the consolidation of arch-girder,two expansions are built for the main span,at the same time,tie bars are set to balance the horizontal thrust of the arch.Through the introduction of the overall design of Xing-wang Bridge,this paper can provide a reference for similar sightseeing bridge design.
