The Disease Analysis And Reinforcement Research Of Prestressed Concrete Tied Arch Bridge

The detection and reinforcement of bridges engineering projects are studied in this paper。Among China's transportation facilities, many bridges already in service at an early stage are in need of tests, detections and reinforcement owing to heavy traffic volumes & loads,materials' aging,saving of materials in construction and design & quality defects, This article detailed in introduction of the application of carbon fiber, bonded steel reinforcement technology and summed up the commonly used bridge inspection and reinforcement methods with the horizontal comparisons of economy and feasibility analysis。The comprehensive applications of bridge detection and reinforcement technologies are discussed in the paper through practice of the two regulations on bridge reinforcement in combination with those specifications not included in the two regulations for concrete norms.
