Research On Endure Of Littoral's Concrete Bridge

This article aimed at littoral's reinforced concrete bridge that was occurred concrete invalidation and structure enduring damage because the execrable ocean climate and the seawater's erode. We carried through the investigation based on Qinkou river bridge of Binzhou city of Shandong province:1:Combined with littoral (Binzhou) actual geography, climate, environment ect. , we analyses cracking reason and mechanism of the origin Qinkou river bridge.2: We carried out high properties concrete's design of gradation of the new Qinkou river bridge and analyses the high properties concrete's workability and mechanics performance.3: For the"double mix"high properties concrete which mixed into mineral and FDN we tested its enduring.4: We put forward design advice of littoral concrete's enduring.We put forward the feasible method for designing enduring of concrete bridge through opening out the actual factor of littoral's enduring of concrete bridge.
