天津安阳桥设计关键技术

该文介绍了天津安阳桥设计的若干关键技术。天津海河安阳桥桥梁建筑艺术设计优美,造型独特,是天津滨海新区中心商务区的新地标,是桥梁建筑艺术与桥梁结构的完美结合。安阳桥为大跨度空间钢网拱桥,软土地基上大跨度拱桥水平推力是一个技术难题。安阳桥主拱为空间钢网拱,主拱刚度较弱,主拱和主梁的刚度匹配,空间主拱的设计,是另一个技术难题。安阳桥为空间拱桥,安阳桥的抗震和抗风性能又是一个值得研究的课题。

Key Design Technology of Tianjin Anyang Bridge

The article introduces some key design technologies of Tianjin Anyang Bridge.Anyang Bridge of Tianjin is beautifully designed and its shape is unique.This bridge is the new landmark of the central business district in Tianjin Binhai New Area and the perfect combination of bridge architectural art with the bridge structure.Anyang Bridge is a long-span spatial steel net arch bridge.The horizontal thrust of long-span arch bridge is a technical difficulty on the soft soil subgrade.The main arch of Anyang Bridge is the spatial steel net arch.The rigidity of the main arch is weaker.The rigidity of the main arch is matched with the main girder.The spatial design of the main arch is the other one technical difficulty.Anyang Bridge is the spatial arch bridge.The seismic and anti-wind performances of Anyang Bridge are worthy of study.
