Concrete materials have high cost, strong compression resistance and so on. But its use can’t achieve the life expectancy, causing serious economic losses. Therefore, a study on the durability of concrete structures in cold and drought area based on the field exposure test was proposed in this paper, and the influence factors of durability of concrete structure was studied. It is proved that the durability of concrete structure is affected by various factors, such as the long-term freezing and thawing cycles in the cold and dry regions, as well as the high concentration of chloride ions and sulfur ions in saline soils, which seriously affect the durability of concrete structure.
