摘　　要：弯桥设计历来是桥梁设计的难点,处理好上部构造(板或梁)与平面曲线半径的关系至关重要。以秦唐高速公路为依托,通过对某小半径互通匝道桥进行布梁方案设计,为同类型小半径曲线梁桥提供设计思路及参考。Curved bridge design has always been a difficult point in bridge design.It is very important to deal with the relationship between superstructure(slab or beam)and plane curve radius.The article is based on the Qinhuangdao to Tangshan s expressway.By designing a beam layout scheme for a small radius interchange ramp bridge,the article provides design ideas and references for similar small radius curved beam bridges.

关 键 词：曲线桥 布梁设计 平行布置 径向布置
