| 中文摘要: |
| 矮塔斜拉桥是介于连续梁桥和普通斜拉桥之间的新型桥梁，其受力以主梁为主，拉索为辅。本文通过有限元软件Midas/Civil建立全桥模型，对主梁最大双悬臂状态及成桥状态进行受力分析。在此基础上提出双塔矮塔斜拉桥结构设计时，应当以施工过程最大内力作为控制截面设计依据并需对0号块进行深入详细的局部分析，以期为同类桥型设计提供参考。 |
| 英文摘要: |
| Low tower cable-stayed bridge is a new type of hybrid structure between continuous bridge and cable-stayed bridge based in the main girder and cable supplement of the force. Finite element software called Midas/Civil was used to built up calculation model of the bridge, then focused on analyzing the structural behavior at the stages as follows: the maximum twin cantilever, end of construction state. On the basis of it, proposes the maximum internal force of construction process shall be the control basis, and need further analysis of NO.0 block of similar bridge, in the hope of providing reference to the similar bridge. |
