摘要
以某大桥加固维修项目为依托工程,采用桥梁专业软件Midas Civil 2019建立结构空间有限元模型,在不中断交通情况下对3跨中承式钢管混凝土拱桥更换吊杆及加劲纵梁进行仿真分析,制定了相应的施工控制方案,并通过了相关计算和测量数据的分析。该加固维修施工达到了预期目标,研究成果对类似工程具有一定的借鉴意义。
Based on a bridge reinforcement maintenance project, Structure spatial finite element model was built by bridge professional software of Midas Civil 2019. Without traffic interrupting, the replacing hangers and adding longitudinal beams of a three-span half-through CFST arch bridge was simulated analyzed. The relevant construction control plan was proposed and verified by calculation and observed data. The project obtained the expected target.The result provides reference for similar projects.
