摘　　要：目前对大跨桥梁，尤其是缆索类大跨结构，如斜拉桥、吊桥等的抗震设计尚无成熟的规范．针对主跨４１４ ｍ 的郧阳汉江公路大桥的设计，介绍了地锚式大跨径 Ｐ Ｃ 斜拉桥抗震设计中跨中接头设计、主塔处主梁横向限位支座的减振设计、合理的预应力体系及普通筋配置、局部设计等措施，说明其抗震设计机理．At present there has not been a mature standard of aseismic design for bridges with long span,especially for cable structures,such as cable stayed bridges and suspension bridges.This paper expounds the aseismic mechanism by introducing the aseismic design measurements concerning mid span joint,vibration segregation for crosswise displacement limit of the mainbeam at the towers,reasonable disposition of prestressed bundles and reinforce bars,partial design of earth anchored cable stayed bridges with long span based on the successful design of Yunyang Han river High Way Bridge with 414 m mainspan.
