中承式钢拱与刚构协作体系慢行系统景观桥设计研究

Research on Landscape Bridge Design of Slow Running System with Cooperative System of Half-through Steel Arch and Rigid Frame

摘要:

随着人民生活品质的不断提升，人们的需求也逐渐升华，对于桥梁不再仅满足于其通行功能，也开始追求桥梁之美。以灵山-横沥组团慢行过江桥梁为例，以景观设计作为出发点，对城市景观中承式钢拱桥的跨径设计、体系设计、结构设计和结构计算进行分析研究，追求力与美完美结合。钢拱桥采用刚性吊杆以及刚性吊杆与遮阳棚骨架结合的设计，提出施工过程张拉临时系杆解决拱桥推力的方法，以期为城市景观钢拱桥桥梁设计提供思路和参考。

Abstract:

With the continuous improvement of people's quality of life, the people's needs are also gradually sublimating. For the bridge, people are no longer satisfied with its passing function, but begin to pursue the beauty of the bridge. Taking Lingshan - Hengli group slow river crossing bridge as an example, the landscape design, the span design, system design, structural design and structural calculations of half-through steel arch bridges in urban landscapes are analyzed and studied, which pursues the perfect combination of strength and beauty. The steel arch bridge is designed of rigid hangers and a combination of rigid hangers and sunshade framework. A method for tensioning the tie rods to solve the thrust of arch bridge during the construction is proposed, which provides the ideas and references for the design of urban landscape steel arch bridges.
