Preliminary Investigation of Influence of Special Testing on Bridge Structure Durability

Abstract:

Based on bridges routine examination, special detection is in-depth and meticulous testing that according to the disease characteristics, using some expertise technology and testing equipment for steel corrosion, concrete carbonization, the thickness of the protective layer and component quality to some key parts or typical bridge opening. Bridge condition of technology can be controlled more fully and accurately through a special bridge inspection, combined with conventional test results on the status of a comprehensive assessment of structures. This may provide technical data for the next bridge inspection count and load test, moreover, according to the variation of the data in the field test, it may dedicate variation characteristic and influencing factors for damage of structural durability from these special detections.
