| 中文摘要: |
| 桥梁合龙是桥梁施工中非常重要的一个环节，合龙次序与解除临时固结时机的不同会对成桥内力和线形状态有较大的影响。文中以九华河大桥为例，采用有限元软件MIDAS Civil 2010分别建立了3个不同合龙次序及解除临时固结的计算模型，对其产生的挠度及应力变化进行了比较分析。为类似预应力连续梁桥设计和施工方案的选择提供参考。 |
| 英文摘要: |
| Closure is a very important part of the construction of bridge, closure order and lift the temporary consolidation time difference can have a significant influence on the internal force and alignment of the bridge state. In this paper, taking a Jiuhua river bridge as the engineering background, established 3 different closure order and lift the temporary consolidation calculation model by the finite element software MIDAS Civil 2010, the deflection and stress change are analyzed. To provide reference for similar prestressed continuous beam bridge design and construction scheme selection. |
