      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.
