| 客运专线预制箱梁终张拉弹性上拱度研究(51卷) |
| 英文标题 |
| Study on elastic camber during final stretching for prefabricated box-girder on passenger-dedicated railway |
| 摘要 |
| 客运专线预制箱梁终张拉弹性上拱度是生产过程中重要的监测参数，也是预拱度设置的依据。为考察终张拉弹性上拱度的实际情况，对5孔箱梁终张拉阶段进行全过程监测，采集每个张拉步骤的位移数据。同时，建立有限元模型，按张拉顺序对终张拉阶段进行模拟，给出了箱梁在不同的二期恒载下终张拉弹性上拱度有限元分析值，与监测数据比较吻合。 |
