The freeze resistance and resistance to ice force of large cylinder pile and PHC pile, additional measures, overall technological scheme and technique-economics for the application of the above-mentioned two kinds of piles in northern seaport wharves are demonstrated. The results show that if the frost resistance of pile concrete is under control and necessary protective measures are taken for the pile in water level fluctuation area and splash zone, meanwhile the ice-retaining pile skirt, manger board and reinforced concrete parapet wall are used to protect the pile in the exposed aera, large cylinder pile and PHC pile can be used in northern open seaport wharf.Moreover, the application prospect is extensive because of the obvious technological advancement and economic efficiency.
