大跨径景观人行桥设计

Design of Long-span Landscape Footbridge

摘要:

随着经济建设的日益发展，担负着疏导人行交通重任的城市人行天桥数量与品质快速提升，并成为城市景观的重要组成部分。在景观人行桥设计中，对安全、合理、经济、舒适、耐久等方面的要求也在不断增加。结合实际工程，介绍了大跨径景观人行桥的设计要点，包括总体布置、结构设计、快速施工、人性化设计、景观优化、长期性能等，相关的设计思路与方法在实桥建设中进行了应用，取得了良好的经济效益与社会效益，可供同类桥梁建设进行参考。

Abstract:

With the increasing development of economic construction, the number and quality of urban footbridges shouldering the important responsibility of guiding pedestrian traffic have rapidly improved, and have become an important component of urban landscape. In the design of landscape footbridges, the requirements of safety, rationality, economy, comfort, durability and other aspects are constantly increasing. Combined with the engineering practice, the design essentials of long-span landscape footbridges, including overall layout, structural design, rapid construction, humanized design, landscape optimization and long-term performance are introduced. The relevant design ideas and methods have been applied in actual bridge construction, and the good economic and social benefits are achieved, which can be used as a reference for the construction of similar bridges.
