Abstract

Abstract

The durability inspection of bridge concrete structures in Rizhao coastal area was carried out. And theinvestigation on cover thickness, carbonation depth and free chloride concentration of bridge concrete was executed.The inspection resulted showed that the concrete cover thickness of bridge structures was less than the designed valueand results in durability problem; the unreasonable structure design, unsuitable construction management, shortagemaintenance and excess load were the main reasons of damage to coastal bridges. Moreover, the ingressive chlorideand carbonation would lead to corrosion of steel bar in bridge structures. And the crystalline salt would result inphysical deterioration of bridge concrete.
