In view of the difficulties in the structural design of overseas wharf in open sea and strong seismic areas,taking the project of 2×300 MW coal-fired power plant in Mariveles,Philippines as an example,we analyze the characteristics of the structure bearing wave load and earthquake load,carry out the differential selection of structural displacement limit standard under different working conditions,study the influence of adaptability of cemented geology to pile foundation,and determine to select the wharf structural form of the full straight piles with lower berthing and mooring platform.The results show that this design scheme can adapt to the environmental impact of large waves and strong earthquakes,the foundation can well adapt to the geological conditions,and the structural displacement can be well controlled during the operation period.
