Temperature stress analysis of highway bridge in high altitude cold and arid regions
With the continuous progress of bridge construction technology,the shape and structure of the high-way bridge are also updated,and the temperature influence to the safety and durability of the bridge is becoming more and more prominent.Especially in high altitude areas such as Qinghai,the influence of temperature stress in bridges is more obvious due to the large temperature difference and sufficient sunshine.Based on the meaning of bridge temperature stress,this paper analyzes the causes of temperature stress,and analyzes the influence of tem-perature on long-span continuous box girder bridge in high altitude area based on the calculation of temperature stress in construction projects,provides reference for similar projects.
