摘要
在明确悬臂施工的大跨连续梁桥具体施工过程的基础上,对其进行施工至成桥全过程力学性能分析,以此为基础对其进行详细的设计,进一步明确具体的设计过程和验算内容。结果表明,所设计的桥梁满足相关规范的要求,具有一定的强度和刚度储备。有关经验对同类型的桥梁工程建设和设计具有一定借鉴作用。
Based on the detailed construction process of a long-span continuous girder bridge constructed by cantilever construction method,the mechanical properties are analyzed from construction to completion.Then the bridge is designed in detail,and the design process and the check contents are further clarified.The results show that the designed bridges satisfy the requirements of the guidelines and have the corresponding strength and stiffness margins.The relative experience can be usefully referred for the construction and design of the similar bridge projects.
