城市轨道交通高架桥的景观美学设计

Aesthetics in the Landscape Design of Viaducts in Urban Rail Transit

说明景观是视觉的结果、美学是感官的享受,轨道交通高架桥是由多个元素组成的综合系统工程,将城市轨道交通高架桥作为景观设计意义重大。从轨道交通高架桥自身的结构体系(即桥型、梁墩、桥高、桥梁跨度、桥高与跨度的比例关系、梁高与跨度的比例关系、梁高与墩宽的比例关系)、桥梁美化与周边环境的整体协调等方面入手,系统阐述城市轨道交通高架桥在美观服从于自身结构功能前提下的景观美学设计。

Landscape is the visual result of human. Rail transit viaduct is an integrated systematic engineering project composed of a lot of elements. It is of great significance to regard urban rail viaduct design as the landscape design. This paper systematically describes the aesthetics in the landscape design of viaducts under the premise that beauty is subordinate to structure functions and considering the following aspects of bridge structures： the types, pier, height, and span of a bridge, ratio of the height of the bridge to the span, ratio of the height to width of the girder, ratio of height of the girder to the width of the pier, coordination between bridge beautification and the environment.
