| 铁路大跨度连续刚构柔性拱主梁施工监控技术研究(51卷) |
| 英文标题 |
| Study on construction supervision for main girder of railway large-span continuous rigid framed flexible arch bridge |
| 摘要 |
| 本文以新建广珠铁路西江特大桥主桥为依托，探讨了大跨度连续刚构柔性拱桥主梁施工监控的方法，结合结构有限元仿真分析，在施工过程中对结构线形、挂篮变形、截面应力进行监测，通过实测数据进行参数识别与误差分析，指导现场施工。实践表明，大桥主梁合龙后线形在设计运行误差范围内，结构受力正常，施工监控效果良好。 |
