| 大跨度混凝土斜拉桥施工控制正装和倒拆仿真分析(49 卷) |
| 英文标题 |
| Simulation analysis on process of assembling and dismantling of members under construction control for large-span concrete cable-stayed bridge |
| 摘要 |
| 以有限元理论为基础，结合斜拉桥施工控制理论，运用软件Midas/Civil模拟分析斜拉桥施工过程，分别采用正装法和倒拆法计算分析马桑溪大桥施工过程中结构的受力特点，重点探讨两种模拟方法对结构变形及内力的影响规律及原因。计算结果表明，由于施工过程中存在着体系转换，正装 |
