Study On Testing And Conservation Technique For Concrete Filled Steel Tubular Arch Bridge

With incomplete statistics, China has built more than100m span CFST arch bridge has reached more than300seats. By arch bridge structure is complex, many structural components, coupled with our technological bridge maintenance teams generally weak, and there are many arch bridge appears diseases, it is necessary to carry out arch bridge inspection and maintenance technology research to improve their life and reliability. The main contents are:1, steel tube concrete arch bridge mechanism or cause of Void and study of existing detection techniques.2, boom boom diseases and cable force detection technology boom anchor head under water rehabilitation program research.3, Arch Bridge linear detection and monitoring technology.4, prestressed concrete anchorage zone end appearance quality; beams and concrete anchorage zone of the upper and lower boom appearance quality detection and monitoring technology.5, Ningde City, Fujian Province, Funing Road2nd bridge arch bridge major disease research.6, Ningde City, Fujian Province, Funing Road2nd bridge arch bridge monitoring scheme.
