Damage And Reinforce Technology Of Concrete Bridge Structure

All the newly-built bridge will be sure to become old ones in the end. In order to keep the bridge in order, the bridge should be maintained, reinforced, and transformed. the uniformity and continuity of the Concrete materials are not as good as those of metal. These systemic shortages cause the mechanism of concrete damage that kinds of microcracks come into being and develop into macrocracks.only when combined with the integral damage identification and evaluation methods can traditional detection methods of bridges forecast the degeneration of the whole structure function.This paper takes Dadiangang Bridge as an example and chooses proper mechanics model to analyze and ascertain the positions and reasons of its damage; uses the detection, load test results and damage theories to make damage identification and the study of its function.
