| Abstract: | After many years of operation, the bearing capacity of some pre-stressed concrete bridges is not as great as before. The main diseases are the miscellaneous cracks in the concrete beam body of box girders. The formation of cracks in practical engineering is the result of combined action of many factors due to the hidden dangers of construction and the untimely routine maintenance. |

| Keywords: | concrete beam body of box girder cracks combined action |
