异型板桥作为城市立交中一种特殊的桥梁结构形式,具有建筑高度低、外形可塑性及适应性强、线型流畅美观、结构受力合理、施工方便及很好的经济效益和社会效益等优点,在城市立交发展中扮演了重要的角色。由于外形的随意性及板式结构受力的特点,异形板结构受力特性一般比较复杂。本文以工程实例为基础,归纳了异型板桥的特点,并提出了异型板桥的一些计算要点及构造特点,供类似工程设计参考借鉴。
As a special type of bridge structure in the urban interchange, the special-shaped slab bridge has the advantages of low building height, plasticity and adaptability of shape, smooth and beautiful line, reasonable structure, reasonable construction, convenient construction and good economic and social benefits , Played an important role in the development of urban interchange. Due to the randomness of the shape and the force of the plate structure, the stress characteristics of the special-shaped plate structure are generally more complicated. Based on the engineering examples, this paper summarizes the characteristics of the special-shaped slab bridge and presents some calculation points and structural features of the special-shaped slab bridge for reference of similar engineering design.
