Abstract


Continuous rigid frame bridge application in China is more common , but the building in the form of complex geographical environment , rivers, mountains hills many reasons for showing a variety of different forms . Meanwhile, China is an earthquake-prone country , after the completion of the continuous rigid frame bridge once a failure occurs in the earthquake , will cause great economic loss and even loss of life . So long span continuous rigid frame bridge seismic response analysis provides some scientific basis for bridge seismic safety design has very important significance . Earthquake observed vibration and deformation will occur in deep water piers and cause the surrounding water sloshing water Youyi moving water pressure in the form of reaction at the pier , thus changing the vibration of the bridge structure and deformation state . This kind of action and reaction accompanied by earthquake always . In this paper, the seismic response analysis on the basis of the basic theory , long span deep water pier white jianhe Bridge Engineering instances , according to the highway bridge seismic design of the new \and time history analysis . The main contents include: dialogue jianhe Bridge establish the finite element model , MIDAS / Civil software ; consider vertical seismic based on analysis of the pile - soil interaction on seismic response of the bridge ; 3 , in considering the vertical to the earthquake and the pile - soil interaction based on seismic Analysis and Record of seismic waves E1 earthquake response spectrum analysis , focusing on the analysis of the deep-water bridge seismic response . The study of these issues can provide a useful reference for the seismic design of similar bridges .
