Human beings always suffer huge lost in natural disasters, particularly earthquake, which directly brings catastrophic consequences. Aimed at this, scholars intensify relevant facilities and perfect the structure of affected buildings at all aspects. Regarding earthquake, measures are taken to increase the strength of some earthquake prevention materials and change the construction spot or structure that are in-conformity with the seismic safety evaluation. Bridge, as an important composition of communication, calls for improvement for its earthquake prevention. To begin with, the paper discussed the difference between the dynamic characteristics of cable-stayed bridge and its approach bridges. A bridge was applied as research object, and the influences of coupling beam device on the collision response between cable-stayed bridge and its approach bridges were investigated by analyzing the models, ground motion input, seismic influences and bridge structure parameters. Furthermore, several improvement suggestions were put forward. The research provided reference for the construction of cable-stayed bridge with ideal dynamic characteristics and theoretical basis for reducing damages that induced by the collision of cable-stayed bridge and its approach bridges.
