摘　　要：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。Special-shaped-slab bridges play an important role in urban interchange design because of their smaller height,variable and flexible shape,reasonable structural force,convenient construction process,good economic and social benefits.The analysis of the slab bridges is complicated because of its variable shape and mechanical characteristic. Based on previous engineering projects,the structure characteristics of special-shaped-slab bridges were analyzed, and some key points on calculation were given out.It can be applied as a reference in the same kind of design.
