Problems and Reflections of Bridge Technical Condition Assessment
With the continuous construction of China's infrastructure,highway mileage is growing,and the total number of highway bridges is over one million,with amounts of bridges entering the cycle of curing-detection-maintenance-curing.Periodic detection is a crucial basis for the curing and maintenance of highway bridges,and its results directly affect the decision-making of the maintenance management department.Focusing on the detected diseases of simply supported to continuously prestressed small box girders such as vertical cracks in girder webs,bar corrosions,block diseases,and abutment drainage conditions in the periodic detection,this paper proposed its understanding and suggestions,hoping to provide a reference for detection and maintenance worker.
