徐州310国道中运河连续梁桥拆除施工监控研究

Study on Construction Monitoring of Canal Continuous Beam Bridge Demolition on Xuzhou 310 National Road

随着城市化进程的加速,城市桥梁建设已成为城市发展的重要组成部分。然而,随着时间的推移,许多桥梁已接近或已达到设计寿命,导致拆除或更新需求日益紧迫。预应力连续梁桥作为被广泛采用的桥梁类型,其拆除过程备受关注。该研究以徐州310国道中运河连续梁桥拆除为案例,结合有限元模拟和实测数据,分析了拆除过程中的关键问题,并提出了施工预警值,为安全施工提供了可靠的数据支持。结果表明,虽然温度变化对结构有显著影响,但拆除后桥梁整体恢复较为稳定。

As urbanization speeds up,building bridges has become a crucial part of city growth.But as time goes on,many of these bridges are getting old,reaching their limits,and need to be torn down or upgraded.One popular type of bridge,the prestressed continuous beam bridge,is getting a lot of attention in this regard.This study took a look at how they tore down a continuous beam bridge on the Xuzhou 310 National Road as an example.By using computer models and real-life data,they figured out the main problems and suggested ways to make sure the demolition work was done safely.What they found was that while temperature changes could mess with the bridge's structure,overall,things settled down pretty well after it was torn down.
