| Abstract: |
Shiziyang link Project, with an investment of approximately 40 billion RMB, is a landmark project in the Guangdong-Hong Kong-Macao Greater Bay Area. The main bridge is a 2180m double-decker, 8+8 lane suspension bridge, which will become the largest span double deck truss girder suspension bridge in the world. The lower deck adopts closed-box girder, and the upper deck adopts open girder. The upper and lower decks are connected by warren trusses. The tower adopts steel-concrete composite tower. The main cable uses high-strength steel wires with zinc-aluminum alloy coatings, possessing a tensile strength of 2060MPa. The long hangers are provided with anti-thrust cable clamps. Gravity anchorage adopts circular diaphragm wall foundation. |
