Analysis on Construction Control of Continuous Rigid Frame Bridge in Winter Intermission

摘要

Cantilever construction has been commonly used in construction of continuous rigid frame bridge and construction control plays an important role in ensuring the line-type and the forced state. Because of long construction period, it tends to construct across the winter possibly. Considering that the impact of winter intermission on construction control of pre-camber is a problem which the constructors and control staff must pay attention to, this paper takes the impact of winter intermission on construction stage into consideration. The research has guiding significance for the construction of the similar bridge to a certain degree.
