本文以位于木里县的达娃二桥为工程背景，利用反应谱法进行高墩简支梁桥在E2地震作用下的响应分析，分析对比考虑桩-土相互作用效应与否对高墩简支梁桥地震响应的影响。结果表明：当考虑桩-土相互作用时，结构的体系变的更柔，结构位移变大；主墩的弯矩变小，剪力变化趋势相同，但极值点位置发生变化；主梁的内力变化有大有小。

With the Second Dawa bridge which is located in Muli County as the engi-neering background,the response spectrum method is used for the response analysis of simply supported bridge with high piers under seismic action . During the process,it takes comparative analysis to discuss the ef ect on the seismic response of piers if the pile -soil interaction is considered or not. The results show that the seismic response of two cases are quite dif erent . When the pile-soil interaction is considered,the architecture becomes more flexible,displacement of the structural becomes larger;the bending moment of main piers becomes smal er,The change of Shear has the same trend,but the extreme position is changed;the internal force of main girde changes with dif erent sizes.
