| 桃河特大桥主跨65 m钢—混结合梁施工过程控制(52卷) |
| 英文标题 |
| Construction control over main span of 65 m steel–concrete composite girder of Taohe super large bridge |
| 摘要 |
| 采用虚拟层合板—壳—梁—实体组合单元法对桃河特大桥施工过程进行了有限元仿真分析,并与实测结果进行了对比,得出如下结论： 虚拟层合板—壳—梁—实体组合单元法能够以少量的单元精确模拟结合梁的几何细节,避免了结合梁施工过程力学分析中的重复建模、节点耦合等难题;“U”型钢梁在移梁架设过程中各控制截面的实测应力变化较小,架设过程平稳、顺利;各施工阶段钢梁和钢筋混凝土桥面板应力实测值与理论值较为吻合。 |
