Study on Sunshine Temperature Field of Concrete Box Girder Based on Meteorological Parameters

Abstract In order to analyze the variation law of sunshine temperature field of low height concrete box girder, Tangshan second ring road cable-stayed bridge was used as the engineering background, the finite element method combined with the field temperature measurement is used to analyze the sunshine temperature field of the concrete box girder by using the weather observation data at the bridge site. The results show that: the temperature field of sunshine in the box girder can be directly analyzed using the meteorological observation data at the bridge site, and the calculation precision can meet the engineering requirements.
