| 中文摘要: |
| 自锚式悬索桥空缆线形是保证桥梁成桥状态的关键因素，以上海市浦东新区运河大桥为工程背景，提出了结合有限元施工控制模型与悬链线数值算法的空缆线形计算方法，对空缆线形以及施工过程进行精确分析，解决自锚式悬索桥施工控制残余误差的问题。最后通过对浦东运河大桥的分析，验证了应用此方法进行正装分析的精度以及效率。 |
| 英文摘要: |
| Unloaded cable shape of self anchored suspension bridge is an important factor to ensure the completion state. With Pudong canal bridge as the engineering background, a method to calculate unloaded cable shape considering construction control is proposed. In combination with finite element model and segmental catenary theory, residual error is avoided during construction control of self anchored suspension bridge. The results of the project shows that the proposed method is accurate and fast convergent. |
