Abstract

It is necessary to research the temperature field because corrugated steel web PC combined box girder is made from different material in the roof, floor and web, and temperature distribution in the sunshine is also different. This paper relies on a flyover as the actual engineering background, combing with theory, and comes up with two kinds of distribution patterns of temperature field of this bridge by analyzing data obtained by collecting for 90 days in 32 measuring points of this bridge.Under the influences of sunlight the temperature of corrugated steel webrises rapidly above the concrete roof and floor and its distribution is a special form. In the night, the temperature of corrugated steel web drops rapidly below the concrete roof and floor and its distribution is a vertical C-shaped. And fit sunshine temperature gradient mode suitable for the corrugated steel web PC combined box bridge in Guanzhong area. There is a reference meaning for similar bridges.
