| Abstract: | In this paper,an old bridge's widening and rebuilding construction is set as the research object.By virtue of building 3D models of this bridge,the bearing capacity and dynamic characteristics are analyzed firstly.Then,according to the stress and deflection from field measurement,the influence of bearing capacity and dynamic characteristics to the service performances is obtained.And finally provide theory references for this kind bridge's rebuilding. |
