【 摘 要 】

As a large and complex structural system, each change of physical parameters will have a certain degree of influence on the whole structure. Taking the navigable hole bridge of the main bridge of Yueqing Bay No. 1 Bridge in Zhejiang Province as an example, the influence of concrete bulk density, temperature change, elastic modulus, prestress tensioning, shrinkage plus creep of concrete on the bridge deformation is considered, that is, the sensitivity analysis of parameters. Thus, the parameters together with their effects which have a great influence on the structure in the process of bridge construction are determined and adjusted in time to ensure the linear smoothness of the bridge, the safety of the structure, and the improvement of the driving comfort and the aesthetics of the bridge.
