Study on the Durability of Coastal Area Bridge

The durability of coastal area bridge structures is more prominent, first, the understanding of the durability of the concrete is insufficient before, and the corresponding measures has not taken; Second, accelerating deterioration of the reinforced concrete is due to the environment and climate factors. Experience has shown that both home and abroad: Starting from the design, take preventive protection measures is effective means to improve the durability of reinforced concrete bridge,then it can get twice the result with half the effort. Based on the Tangshan Coastal Highway construction, considering of the leve of the engineering environmental and so on, on the basis of the service life of the bridge design, the durability of concrete structure would be studied.
