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5部分,分析和比较了我国、美国和日本规范中高桩码头的抗震设计方法。比较表明:对于高桩码头抗震设计,我国规范和美国规范采用反应谱法确定地震力,日本规范则将地震危险性分析得到的结果作为输入的地震波,根据结构的反应确定地震系数。美国规范给出了多种码头变形的计算方法。
A comparative study was made on seismic design of port and harbour structures based on Chinese code,US guidelines and Japanese standards as well as guideline of international navigation association.This is the fifth of the series papers and the method for seismic design of pile-supported wharf in these codes is analyzed.It is shown that for the design of pile-supported wharf,the response force generated by earthquake is determined based on acceleration response spectrum in Chinese code and spectrum acceleration in US guidelines,and the seismic coefficient obtained from analysis of seismic hazard and dynamic response of structures is used in Japanese standard.Several approaches are presented in US guidelines for deformation prediction.
