摘　　要：由于我国与国外同类港口工程岸坡抗震设计规范相比,在设计理念和设计方法等方面存在较大差异,这使设计人员难以适应海外项目的抗震设计要求,在很大程度上制约了海外项目的顺利实施。收集并归纳了美国标准中码头岸坡抗震设计的流程和具体操作方法,重点介绍了土体液化判别、拟静力法边坡稳定分析、土体液化残余强度和Newmark滑块位移法,并提供了一个按照美国抗震标准进行码头岸坡抗震设计的案例,为今后国外类似工程抗震设计提供参考。Compared with foreign countries’seismic design of slope,there are significant differences in Chinese design concept and design method.Therefore,it is difficult for the designers to adapt to the seismic design requirements of overseas projects,which greatly restricts the smooth implementation of overseas projects.We have collected and summarized the process and specific operation methods of quay slope seismic design in American standard,mainly have introduced the liquefaction evaluation,quasi-static method,the undrained residual strength(Sr)and Newmark method.We provide a case of seismic design of the slope according to the American seismic standard,which can provide reference for future seismic slope design of foreign project.
