Research conclusions: Many rapid constriction technologies were used for the foundation construction and erection of the superstructure. The applicable results show ： (1) Application of the standardized constriction for the trestle bridge and application of the rapid and safe member can make the turnover rate of the member more rapid and the manufacture and erection costs lower. (2 ) Application of suspension box - cofferdam which is sub - sealed with funnel instead of concrete for the cushion cap of the main pier, can effectively reduce the concrete quantity for sealing The bottom，lighten the design weight of Coffer dam and shorten the construction period of cushion cap and cut the cost by 50% . ( 3 ) For construction of the superstructure，application of the one - end - cantilever - assemble way along with the temporary stay cables fixed between stiffening beams of medium span can overcame the problem of strength deficiency of the main beams when the utmost cantilever is assembled，much reduce the crane amount， have no assisting cable tower and temporary piers within the span and cut the cost by 80% . (4) For construction of the main beam, application of the erection method that the beam is not jacked up on the main piles while the beam is jacked up or laid down on the side piers can reduce the large jack quantity and ensure the construction safety, getting the notable economical effect . (5) This rapid construction method for the bridge can provide the reference to construction of cushion cap and erection of the upper stiffened continuous steel truss bridge affected by tide.
