摘要
分析了三跨一联连续梁桥满堂支架施工存在的风险,用MIDAS/Civil程序分析计算了支架结构的强度、刚度和稳定性。通过调整主梁结构设计和施工工艺,保证了桥梁施工的安全性。在此基础上,用GQJS分析了主梁各施工阶段的结构内力和变形,为施工控制提供了理论基础。
The paper analyzed the joint construction risks with full support of a three-span continuous beam bridge. With MIDAS/Civil procedure, the author calculated the strength, rigidity and stability of the support structure. By adjusting the main beam design and construction process, the safety of bridge construction is assured. On this basis, the author analyzed the internal force and deformation of the main beam with GQJS of every construction phase to provide a theoretical basis for construction control.
