Aiming at the problem of large tidal range in the construction of seaports in some sea areas,we design to adopt precast structure at the lower layer of all the beams,change the concrete fender baffle to steel material,and cancel the shear key after specific test to shorten the time of waterwork.To deal with the anti-corrosion problem of steel piles around the spash zone,we use the composite piles. For the construction,according to the work period analysis and tide forecast,we propose that the barge shall berth at tide and the mooring cable,and be loosened and tightened from time to time. It is recommended to adopt the springboard barge and floating jetty,lift and install steel trestle by the tide,and deal with the difficulty of marine construction by adopting the jacking-up platform for piling and ripple method to reduce the adverse effects of large tidal range. The research result may serve as reference for the project construction under the condition of large tidal range.
