Research on Sunlight Temperature Effect in the Construction Process of Long-span Concrete Bridge Structure

摘要

The key of temperature effect of concrete bridge is to identity the most unfavorable temperature distribution of structure. To analysised the important nodes of structure, the most unfavorable temperature distribution was determined by finiteelement analysis according to the differential equation of heat conduction. The construction technology parameters were more reasonable under the supervision and construction control, which provided a reliable technology basis for safety construction of long-span prestressed concrete bridge and reasonable bridge state.
