| Abstract: | Temperature effect has a large effect to concrete box girder, it is very useful to adopt some measures to decrease the temperature effect of concrete box girder to its force. In addition, the air in box beam has a certain impact on the structure durability. The reducing measures of its function are briefly discussed on the basis of this. |
