摘　　要：应用通用数值分析程序,采用等效线性方法计算在地震力激励下,桩长对桩-土-上部结构相互作用体系动力反应的影响,计算结果表明:随着桩长的增加,结构的最大侧移增量减小,结构底部摇摆角随桩长而减小,而结构底部最大剪力随桩长的增加而增大,但顶部楼层最大剪力随桩长变化不明显。The effect of pile length on the dynamic response of pile-soil-superstructure system under earthquake force excitation is calculated by using the general numerical analysis program.The results showed that with increase of pile length,The maximum lateral increment of the structure decreases,The rocking angle of the bottom decreases with the pile length.The maximum shear force increases with increase of pile length,but the maximum shear force of the top floors does not change significantly with the pile length.

关 键 词：刚性地基 动力相互作用 等效线性
