摘要
以川气东送野三河悬索跨越为工程背景,针对悬索结构施工中鞍座顶推问题进行研究。通过建立全桥有限元模型,进行施工模拟分析,结合现场施工情况在确保结构安全及线形合理的情况下调整鞍座顶推方案,并通过施工过程监控数据来验证方案调整的可行性。
Combining the Yesanhe suspension bridge,the paper analyzed the problem of main saddle＇s pushing in suspension structure construction.Through the establishment of full-bridge finite element model for the construction simulation analysis,combining on-site construction work,the paper ensured the structural safety and reasonable linear to adjust the saddle push program,and the monitoring data verified the feasibility of the program.
