Abstract: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.
Keywords:Ji Canal  fish-belly beam  non-uniform  longitudinal transverse  node  landscape
