| 英文摘要: |
| The piers in bridge design are generally hollow thin -walled structures .Due to the influence of many temperature effects in nature the stress distribution of concrete piers is different .Thus hydration heat is different in the process of concrete construction.This paper uses the finite element model to analyze the distribution of the concrete effects under different tempera -ture stress and explores the distribution law of pier body stress at different temperatures , including 5℃construction in winter and 40 ℃construction in summer .Thus provide the basis for the rational design of the pier body structure form and site construction to reduce the heat of hydration . |
