| Abstract: | 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. |
