Research Methods of Applicable and Durable Configurations of Concrete Bridge

摘要

Durability and stress injury of concrete bridge were increasingly prominent on the bridge structure now, the use and safety performances of bridge have been significantly affected. "Applicable and durable configuration" can effectively solve these problems, "applicable and durable" include durability, mechanical properties, enforceability and economy. Impact factors of applicable and durable configuration structural include environmental, vehicle load and material. Combined with the meaning and impact factors of applicable and durable configuration, the proportion of main configurations in whole configurations of concrete bridge and the weight of various factors were identified, and the contents and methods of applicable and durable configuration were determined, which laid the foundation for study of applicable and durable configurations of concrete bridge.
