Influence of Temperature on Elevation of Long Cantilever Box Girder Cast with Balanced Cantilever Method and Countermeasures Against Temperature Influence

With reference to the construction control of several continuous rigid frame bridges and cablestayed bridges, this paper presents the latest research findings about the influence of temperature on the elevation of box girders of longspan bridges cast with balanced cantilever method and the effective ways to reduce the influence of temperature on elevation of the long cantilever box girders. The findings described herewith are of considerable reference to the construction control of other similar kind of longspan bridges.
