摘要
由于城市交通的快速发展,对桥梁美观和结构与周围环境相协调的要求日益增加.大悬臂展翅箱梁结构形式由于其外形美观,在城市高架桥中不断被采用.因此,对这类箱梁结构受力特性进行分析研究,可以解决大悬臂展翅箱梁在设计中的关键技术问题.本文结合大悬臂展翅箱梁建立梁格分析模型,对箱梁不同悬臂长度时,结构重力、汽车荷载等作用下箱梁结构的受力和变形规律进行了计算分析,并作了适当的总结和归纳.
Due to the rapid development of urban transport,the coordination on the appearance and structure of bridges with the surrounding environment is an increasing demand. Because of its beautiful appearance , the structure of large cantilever wing-box girder continues to be used in urban viaduct. Therefore, the study on the force characteristics of this type of structure can solve key technical problems in cantilever wing box girder design. This paper establishes a grillage analysis model to analyze the force and deformation law of large canti-lever wing box girders, which bear weight and other loads and have different cantilever lengths, and accompli-shes appropriate summary.
