| Abstract: | Taking one engineer as an example, the article studies the concrete mechanical performance of site pouring connection section of new and old bridge. The results show that the compressive strength of concrete after vibration has an upward trend, the cleavage strength changes little, the bond stress of reinforcement and concrete decreases evidently. |
