| 摘 要： | 建立了丹江口水库二桥有限元模型，采用Morison修正公式将水对桥的影响转化为附加质量；对比了3种工况下桥梁的自振特性；利用时程分析法分别计算了横桥向及纵桥向地震反应，结果表明：对于高桩承台深水墩连续梁桥水的影响不可忽略。

| Abstract: | The FE analysis model of the second Danjiangkou Bridge was proposed by considering water effect base in Morison formula.The dynamic characteristic of the bridge was discussed and was compared under three different conditions.Time-history analysis method was used to analyze the seismic response of across bridge orientation and along bridge orientation.The results showed that the effect of water can't be ignored to continuous beam bridge with high pier. |

| Keywords: | continuous beam bridge with high pier seismic response time-history analysis method water effect |
