摘　　要：自锚悬索桥在地震作用下最为关心的是塔和梁的响应。基于弹性概念,提出估算钢箱加劲梁自锚式悬索桥地震响应的图表分析法。该方法通过自锚式悬索桥静力分析和自身结构参数,查找对应图表中系数,对方案设计和初步设计阶段结构地震响应给出估算。Under the effect of earthquake the most concerned in selfanchored suspension cable bridge is the response of tower and beam. Based on the elastic concept this paper proposes the chart analysis method for estimation of seismic response of the selfanchored suspension cable bridge with steel box stiffening girder. This method with the help of static analysis for the selfanchored suspension cable bridge and the structural parameters of itself finds out coefficients in corresponding chart, so as to estimate the seismic response of the structure in schematic design and preliminary design stages.
