蓟运河桥纵横向变截面鱼腹梁设计

Design of Longitudinal Transverse Non-uniform Fish-belly Beam for Ji Canal Bridge

随着城市的发展,城市市政交通与公路交通的节点处的桥梁设计必须充分考虑到跨线桥梁的景观设计。详细介绍了位于天津中新生态城内蓟运河上的一座大型变截面箱梁桥。该桥有别于常规的鱼腹梁桥,在纵横向都是变截面,外形圆润流畅,一气呵成。这种桥梁适用于桥下通航或通行要求较低、景观要求较高的场所。

With the urban development,the bridge design at the node of the urban municipal traffic with highway traffic must fully consider the landscape design of overpass bridge.The article introduces in detail a large-sized non-uniform box beam bridge located on Ji Canal within Zhongxin Ecological Area of Tianjin.This bridge is with the longitudinal transverse non-uniform and smooth figure,different from the routine fish-belly beam bridges.This kind of bridge is suitable for navigation or the places with lower traffic requirement and higher landscape requirement.
