| Abstract: | Minpu Bridge is the longest span and scale of double-pylon double-plane double-deck cable-stayed bridge in the world. Its side span is the truss combined beam structure, and has the structural characteristics that its web member is the steel structure, the upper and lower decks are stiffening skeleton packed in concrete. The article summarizes the guiding construction scheme, construction tendering scheme and practical implementation scheme for the design, and discusses the optimization implementation scheme for the structural stress characteristic. |
