摘要
寸滩长江大桥是连接重庆市南岸区弹子石中央商务区、江北两路寸滩保税港区及两江新区的一座跨江大桥,全长1 520m,主跨880m,双向8车道。通过对大桥地理环境和城市文化内核的分析,确定了大桥的景观主题——城市之门。该桥采用双塔悬索桥桥型,在设计过程中,运用符号学的方法,以汉字的书法形式作为桥塔造型的符号载体,融合中国元素的"形"与"意",创作出新颖的"门型"桥塔。桥梁标志涂装色以中国红体现城市精神风貌;锚碇采用透空式造型,简洁而稳定;桥墩造型借鉴了中国传统古建中斗拱的形式,承力明确,古朴优雅;人行道栏杆为栅栏式铸铁栏杆,花板饰以地方文化主题的浮雕图案。全桥景观风格统一,表现了中国元素在现代桥梁景观设计中的创新运用。
The Cuntan Changjiang River Bridge is a river-crossing bridge that connects the Tanzishi central business district located in the south bank region and the Cuntan free trade port area and the Liangjiang New Area in the north bank region.The bridge carries duel eight traffic lanes（four lanes on each side）and is 1 520 min total length,with a main span of 880 m.Based on the analysis of the geological conditions of the bridge as well as the cultural characteristics of the city,the landscape theme of the gate of the city was determined for the bridge.The bridge is designed as a suspension bridge.The two towers are the novel portal-shaped towers created by using the semiotic method,in which the Chinese calligraphy is taken as the semiotic carrier of the shape of the towers,with the consideration of the combination of forms and senses of the Chinese elements.The Chinese red is chosen for the bridge to embody the spirit of the city.The anchor blocks are transparent and hollow structures,which are simple,but do not compromise the structural stability.The piers,inspired by the bucket arches in traditional Chinese buildings,look simple and elegant and have clear load bearing paths.The balustrades are cast-iron railings,the flower plates on which have relief sculptures with local cultural elements.The integral landscape style of the bridge reflects the innovative use of Chinese elements in the landscape design of modern bridges.
