阐述了近期建设的一座横跨威尼斯商业港口的斜拉桥的最终设计改进和工程建设情况。该桥为独塔曲线斜拉桥,采用钢筋混凝土组合结构体系,斜拉索呈单索面锥形布置,桥塔倾斜。桥梁施工方法为采用浮运和大型吊装设备的主梁架设法。主梁体系按照以不锈钢防护壳对其起保护作用的思想进行设计。该桥造型及构造新颖独特,施工技术难度大。桥梁主体结构采用外封装的设计方法,可节约结构用料,同时有助于结构的美学效果和耐久性。
The final design improvement and construction of a recently constructed cable-stayed bridge across the Venetian commercial port are described. The bridge is a single tower curve cable-stayed bridge, the use of reinforced concrete composite structure system, cable stayed cable was cone-shaped arrangement, the tower tilt. The bridge construction method is to adopt the main beam frame of floating and large-scale hoisting equipment. The main girder system is designed according to the idea of protecting it with stainless steel protective shell. The bridge shape and structure of novel and unique, construction technology is very difficult. The main structure of the bridge adopts the design method of outer package, which can save structural materials and at the same time contribute to the aesthetic effect and durability of the structure.
