Research on Field Testing of Mechanical Properties and Durability of Bridge Concrete
In this paper,taking a cross-river bridge in Sichuan Province as an example,the mechanical properties and carbonization depth of bridge concrete were tested by static load test and apparent inspection methods.The results show that the main form of concrete cracks in the bridge is vertical cracks,and most of them occur at the position of the partition board in the bridge structure.The concrete strength of the mid-dle partition board and the roof of the chamber is slightly higher than that of the web of the chamber,and the mechanical properties of the mid-dle partition board,the web of the chamber and the roof of the chamber are good.The durability of concrete of bulkhead and web of bridge is better than that of roof concrete.The corrosion state of steel bars in bridge bulkhead and web plate is better than that of concrete bars in box roof.
