采用有限元分析程序ADINA建立铅芯橡胶支座的有限元模型，通过施加水平循环正弦位移荷载，得出了铅芯橡胶支座的滞回曲线，与试验曲线吻合良好，验证了数值模拟方法的正确性；将铅芯橡胶支座应用到某渡槽实际工程，建立了渡槽-支座-水体的流固耦合抗震分析数值模型，并进行了计算分析；结果表明，运用铅芯橡胶支座后渡槽结构的地震响应显著降低，隔震效果明显，结构抗震性能得到提高。

The finite element model of the lead rubber bearing was established by using ADINA in this study. Through a horizontal cyclic sinusoidal displacement load,the hysteretic curve of lead rubber bearing was ob-tained, which was in good agreement with the test curve and the numerical simulation method was verified. Then the lead rubber bearing was applied to an aqueduct engineering,and a numerical model for fluid-structure coupling seismic analysis of aqueduct-bearing-water was established. The calculation results show that the seis-mic response of aqueduct structures has decreased after using lead rubber bearings, and the vibration isolation ef-fect is obvious, which means the structural seismic performance has been improved.
