摘　　要：我国景观桥梁在美学实现方面目前存在着结构设计规范性与美学设计发散性难以融合,现代城市文化语境下的桥梁内涵难以确当表达,空间复杂异形桥梁结构赋形难以实现等问题,针对这些问题,以大量工程实践为基础,融合交通、土木、建筑等学科理论,进行多学科协同研究.提出基于结构表现、建筑文化、环境协调、体验多元4个维度的景观桥梁创新理念与设计方法,打通景观桥梁从美学、文化理念到工程实现之间的技术路径;提出以解构-重构为核心的结构设计新思想,解决了空间复杂异形桥梁的结构赋形难题.该研究成果在北京冬奥会冰雪五环桥工程中的应用表明,虽然与同类常规桥梁相比,其综合用钢量增加约11%,但在景观上实现了打造标志性文化名片的设计目标,社会效益丰厚.At present, in terms of aesthetic realization of landscape bridges in China, it is difficult to integrate the standardization of structural design and the divergence of aesthetic design, to express the connotation of bridge in the context of modern urban culture, and to design complex and special-shaped bridge structures. Aiming at such difficult problems, this research was based on a large number of engineering projects, and integrated the theories of transportation, civil engineering, architecture and other disciplines to conduct multidisciplinary collaborative research. A four-dimensional innovative concept and design method of landscape bridges, based on structural performance, architectural culture, environmental coordination, and diverse experience, were proposed. A technical path was opened up through aesthetics, cultural concepts and engineering realization of landscape bridges. A new idea of structural design with deconstruction-reconstruction as the core was proposed, which solved the structural shaping problem of complex special-shaped bridges in 3 D-space. Through the application of Five-Ice-Ring Bridge project for the 2022 Beijing Winter Olympics, although the comprehensive steel consumption was increased by about 11% compared with similar conventional bridges, the design goal of creating an cultural icon was achieved in the landscape design with huge amount of social benefits.
