摘　　要：以我国、美国和日本的港口码头设计规范、手册为基础,对我国、美国和日本港口码头抗震设计的方法进行了分析,同时介绍了国际航运协会标准《港口结构抗震设计指南》的有关规定。此系列论文共分6部分,该文为第4部分,分析和比较了我国、美国和日本规范中重力式码头和板桩码头抗震设计的方法。比较表明,对于重力式码头抗震设计,我国规范计算惯性力时考虑了加速度系数沿码头高度的变化,日本规范在基于地震危险性分析结果确定的地震系数中包含着要求控制的变形。对于板桩码头抗震设计,我国、美国和日本规范计算拉杆拉力和板桩墙弯矩时采用的方法不同。A comparative study was made on seismic design of port and harbor structures based on the Chinese code, US guidelines and Japanese standards as well as guideline of International navigation association. This is the fourth of the series papers and briefing the methods of design of gravity type quay wall and sheet pile bulkhead. It is shown that, for the design of gravity type quay wall, the seismic coefficient is height-dependent in Chinese code and deformation-decisive which is based on analysis of seismic hazard in Japanese standard. For the design of anchored sheet pile bulkhead, the method for computing tie rod force and moment in sheet pile are different in these codes.
