斜跨拱桥的拱肋斜跨主梁。针对该桥型的结构形式和受力特点,就其概念设计、细部构造等关键性技术问题展开讨论。以大连市红星海世界观景观桥为例,对该桥型各部分结构的力学性能进行了分析,旨在使斜跨拱桥体系的设计得到进一步的优化。 Diagonal arch bridge diagonally across the main beam. According to the structure and force characteristics of this bridge type, the key technical issues such as conceptual design and detailed structure are discussed. Taking Dalian Hongxinghai World Landscape Bridge as an example, the mechanical properties of various parts of the bridge type structure are analyzed in order to further optimize the design of the diagonal - span arch bridge system.
