The continuous rigid frame bridge is one of the main bridge types used to span rivers in mountainous areas due to its high rigidity. However, due to the poor geological conditions in mountainous areas, the probability of instability and other safety accidents increases. Therefore, strict construction scheme design must be carried out. According to the cast-in-place section of the side span of a continuous rigid frame bridge in a mountainous area, this paper puts forward three construction schemes that may be applicable. The finite element software is used to establish the model, and the girder stress and bridge alignment with different construction schemes are analyzed. Combined with the grading index evaluation method, the optimal construction scheme is finally obtained.
