| 摘 要： | 在Penz ien模型的基础上,建立了独塔斜拉桥考虑桩土相互作用的计算模型,推导了其运动方程,分析了桩土相互作用对斜拉桥地震响应的影响,同时,对地震动自由场输入和桩端输入对独塔斜拉桥的影响进行了比较,分析结果表明:桩土相互作用对独塔斜拉桥地震响应有一定的影响,但它比相应的刚性简支梁小。

| Abstract: | Based on the model of Penzien,the calculation model of single-tower cable stayed bridge in consideration of pile-soil interaction is established,the vibration equation is derived,and the affect of interaction of pile-soil to single-tower cable stayed bridge is analyzed.At the same time,the affect to cable stayed bridge by the input of freedom ground or end of pile is compared.The analysis shows that the interaction of pile-soil has some affect to single tower cable stayed bridge,which is smaller than that of rigidity beam bridge. |

| Keywords: | pile-soil single-tower cable stayed bridge response of earthquake freedom ground end of pile |
