摘　　要：为了提高我国高桩码头的抗震能力,采用ANSYS对天津市塘沽区新河外运码头进行了时程分析,重点探讨了高桩码头在不同烈度地震影响下叉桩及其承台的受力状态和震害原因,并在此基础上提出了叉桩及其承台的设计建议。An example of Pile-Wharf located on the XinHe River in Tanggu, Tianjin was analyzed by ANSYS to improve the seismic capability of pile-wharf. Dynamic responses of batter-piles and its caps under the different earthquake intensity were calculated by the time-history method. The causes of destruction in Tangshan earthquake were explored. Design suggestions on batter-piles and its caps were given on these facts in this paper.
