摘　　要：横跨巴拿马运河第二桥为主跨420 m的斜拉桥,介绍了该桥主跨长且处于强烈地震带情况下确定设计标准时所选用的不同规范,并对该桥潜在的地震风险进行全面的分析,对该桥的主塔结构、斜拉索的造型、桥跨的布局、上部结构进行了研究和设计。The second bridge crossing the Panama Canal is a cable - stayed bridge with a main span of 420 m. Because of the bridge＇s long main span and the potential for strong seismic activity in the area, several different design codes were used in developing the design criteria for the bridge, all of which are introduced in this article. Besides, This essay also introduces a thorough analysis of the seismic hazards at this site, and the investigation and design of the main tower configuration, the cable configuration, the span layout and the superstructure cross section as well.
