Due to the effect of concrete shrinkage, bridge alignment and internal force can be influenced in the process of construction. Taking a three-span prestressed concrete continuous bridge as an example, a finite element analytical model was built by using Midas Civil FEM software. The effect of parameters such as environmental relative humidity, loading age and bridge operation period have on internal force distribution and displacement response of Concrete girder caused by shrinkage effect were obtained in this paper. Based on the analysis of three controllable factors mentioned above, a conclusion was drawn that shrinkage effects were going up along with the increase of environmental relative humidity and bridge operation period, and going down when loading age was put off. Therefore, depending on the sensitivities of vertical displacement and internal force response of concrete girders, advice to reduce shrinkage effects in the construction process was listed in this paper.
