摘　　要：厦门至漳州高速公路全长约18 km,为厦门市重要交通枢纽工程。该高速公路高架桥穿过海沧工业区,景观轴线视点丰富,其设计不仅需满足受力安全要求,还需满足桥梁美学需求。梁型设计方面,选取与周围环境相融合且造型优美的斜腹式箱梁代替厦门市区常见的鱼腹式箱梁,并通过不断调整其腹板斜度及变化处倒角半径对斜腹式箱梁断面进行优化,实现梁型的轻盈、柔美。桥墩设计方面,经比选,全线高架桥选取造型轻盈、视线通透的直立花瓶墩,墩群之间富有较强的节奏感和韵律美。桥梁色彩、夜景及灯光设计等方面,选取浅灰色作为主色调,采用LED线型灯装饰桥梁轮廓,采用投光灯装饰桥墩,将桥下照明设施设置于主梁斜腹板上,使桥梁现代、时尚,并最终实现桥梁景观与自然环境的和谐统一。Xiamen-Zhangzhou Expressway,with a total length of 18 km,is an important transportation hub project in Xiamen.The elevated section of the expressway traverses the Haicang Industrial Zone,creating an array of vantage points for enjoying the landscape along the axis.The design of the elevated expressway is required to fulfill both the load bearing and aesthetic expectations.The box girders with inclined webs,instead of the commonly-seen fish-bellied box girders in the urban bridges in Xiamen,are selected for the superstructure,which are considered aesthetically pleasing and matching well with the surroundings.The inclination angles and radii of chamfers at the varying points of webs are modified to find the optimal cross-section of the box girder with inclined webs,to finally create a slender and elegant superstructure.All the piers are vase-shaped structures,which are visually slim and with better light penetration.The pier groups are rhythmically spaced.Light grey is the dominant color of the bridge.LED line lights depict the silhouette of the bridge at night.The piers are ornamented with floodlights and fixtures are fitted on the inclined webs to make the bridge look modern and stylish and in harmony with the natural surroundings as well.
