摘要
松原天河大桥主桥为空间主缆组合梁自锚式悬索桥,北汊桥主跨为266 m。详细介绍了桥梁的建设条件、方案构思、桥型总体设计和具体结构设计,并针对主缆矢跨比、空间缆索索夹定位、结构抗震性能等关键技术问题的研究论证做了简要介绍。
The main bridge of Songyuan Tianhe River Bridge is the space main cable composite beam self-anchorage suspension bridge. The main span of Beicha Bridge is 226 m. The article introduces the construction condition, scheme conception, overall bridge design and detailed structural design of bridge in detail. The article briefly introduces the study demonstration of the key technical issues of main cable rise span ratio, space cable rope clip positioning and structure seismic performance.
