Abstract Research purposes: Considering the variations of flexibility, stress and geometrical configuration of large span curved continuous beam or continuous rigid frame bridge in the course of construction, the study is done on the issues of flexibility and geometrical configuration control and stress measurement.
Research results: The speck analytical and controlling method for flexibility and configuration control and stress measurement in beam with cantilever wall basket constructing method has been presented. The results show that the flexibility and configuration of the bridge adequately confirm with requirements of design and bridge construction codes.
