Abstract
Cantilever casting construction has been commonly used in construction of continuous rigid frame bridge and the implementation of construction control plays an important role in ensuring the line-type of built bridges and the forced state in construction stage is within the design requirements range. It tends to construct across the winter possibly. Based on an analysis of a typical continuous rigid frame bridge construction stage, this paper takes the impact of winter intermission on pre-camber in construction stage into consideration and the research has guiding significance for the construction of the similar bridge to a certain degree.
