Abstract: The durability status of concrete structure is one of the severe problems of concern in domestic and overseas, in many countries, research of durability has developed in varying degrees. Configurations play important roles in durability of concrete bridge, but researches of them are comparatively less, and there are many problems existed, so research of configurations should be strengthened. Based on the purpose of research, the technical routes and methods as follows should be taken by research of configurations: investigation and analysis of applicability and durability of configurations in domestic and overseas, expenmental research on the results ofinvestigation and analysis, making of design principle and method of applicable and durable configurations, compilation of design manual of applicable and durable configurations. The results of research would do advantages to design, constitution and maintenance of concrete bridge.
