RESEARCH ON THE TESTING METHODS FOR OLD CONCRETE BRIDGE STRUCTURES IN A CERTAIN CITY
Bridges are the connecting network of urban infrastructure and important components of urban transporta-tion. The health status of some old bridges in cities changes under the interference of uncertain factors such as natu-ral conditions and overloaded service. Taking an old overpass in a certain city as the case, a comprehensive evalua-tion and accurate analysis of the bridge structure status are proposed to evaluate the current service status of the old bridge in the city and identify existing problems. The service status of the bridge structure is analyzed by comparing and analyzing the appearance inspection, and static load testing and dynamic testing data of the bridge. The results show that it does not affect the safety of the bridge under normal use, although the overall integrity of the bridge has decreased, which may provide the reference for the detection of the health status of other bridges.
