摘要
长江主轴桥梁是武汉现代化建设中提升生态特色和实现经济、科技、文化等领域升级发展规划的重要载体,因此对武汉跨江桥梁开展视觉优化实践能够集中展示城市文化价值和地域风貌,是加速城市整体发展的有效途径。文中结合城市文化和生态特色建立桥梁色彩分析设计的三元耦合模型,根据模型实地调研武汉8座新旧长江主轴桥梁的桥身涂装和空间景观色彩,通过色彩空间混合方法识别跨江主轴桥梁的空间色彩分布,同时运用直方图分析统计对应的色彩分布情况,并采用K-Means聚类算法提取空间景观的色彩特征;验证色彩空间混合、直方图法与K-Means聚类算法在色彩分布与特征分析方面的可行性,得出长江主轴桥梁的空间色彩分布规律,并探究了桥梁视觉色彩优化设计对城市景观带来的积极影响,进而提出对应的彩化设计策略;获取武汉跨江主轴桥梁的桥体和空间景观的色彩特征,结合城市文化特征对武汉新旧跨江桥梁进行整体的视觉优化设计,从色彩识别分析、色彩分布特征、色彩设计组成3个层面强化特征色彩在桥梁视觉优化设计上的应用,打造了城市桥梁景观轴线。
The Yangtze River main shaft bridge is an important carrier to improve the ecological characteristics and realize the upgrading and development planning in the fields of economy,science,technology and culture in the modernization of Wuhan.Therefore,the Visual Optimization Practice of river main shaft bridges in Wuhan can focus on displaying the urban cultural value and regional style,and it is an effective way to accelerate the overall development of the city.Combined with the urban culture and ecological characteristics,the ternary coupling model of bridge color analysis and design is established.The bridge body and spatial landscape color of 8 old and new Yangtze River main bridges in Wuhan are investigated on the spot.Then,the spatial color distribution of the bridge crossing the Yangtze River main axis is identified by the color space mixing method.Meanwhile,the histogram analysis is used to count the corresponding color distribution,and the K-Means clustering algorithm is used to extract the color characteristics of the spatial landscape.Verify the feasibility of color space mixing,histogram method and K-Means clustering algorithm in color distribution and feature analysis.Obtain the spatial color distribution law of the Yangtze River main shaft bridge,and explore the positive impact of the bridge visual color optimization design on the urban landscape,then put forward the corresponding color design strategy.Considering the urban culture,color characteristics of the bridge body and spatial landscape of the main bridges in Wuhan,this paper investigates the overall visual optimization design of the old and new bridges across the river in Wuhan,strengthens the application of characteristic color in the visual optimization design of the bridge from three aspects:color recognition analysis,color distribution characteristics and color design,and creates the urban bridge landscape axis.
