Abstract：In order to ensure the service life of bearing platform in cross-sea bridge and shorten the maintenance cost，
combining with construction experience of bearing platform in cross-sea bridge and marine environment characteristics，this
paper analyzes the reason of corrosion of bearing platform suffered and mechanism as well as the current all kinds of
anticorrosion methods advantages and limitations，it explores a new technology of anticorrosive from design, subdivisional work
when bearing platform was constructing and later maintenance，the result indicates that new technology which applied in
bearing platform in latest cross-sea bridge obtained good effect，the advantages of construction may be adopted in other similar
bridge.
