Abstract: The durability status of concrete structure is one of the severe problems of concern in domestic and overseas, but the research of concrete structure durability is mainly focused on materials and components of structures. As one form ofconcrete structures, the concrete bridge has it's features, so research ofconcrete bridge should add the contents of applicable and durable configurations. Based on the survey and analysis about causes of durability deterioration, research of configurations should be taken as follows: reinforcing formation, configuration of prestressed system, configuration of hinge joint, connection construction of diaphragm plate, configuration of bridge deck, configuration durability of components, configuration of waterproof and drainage, configuration of repairing and replacement. According to various configurations, these researches take different methods, to determine the applicable and durable configurations of concrete bridge.
Keywords: concrete bridge; applicable and durable; configuration
