Abstract In order to study the seismic response and seismic isolation technology of long-span half-through steel box tied arch bridge under high-intensity earthquake, taking Xishuangbanna Liming Bridge as the engineering background, the actual ground motion records of similar sites were selected as input seismic waves, and the nonlinear time history analysis method was used to study the seismic isolation effect of bearing type and parameter change on arch bridge structure. The results show that compared with the ordinary bearing, the seismic isolation bearing can greatly reduce the internal force of the structure, but the longitudinal displacement increases, and the seismic isolation effect of the friction pendulum bearing is stronger than that of the lead rubber bearing. The combined seismic system of friction pendulum bearing and viscous damper can effectively reduce the longitudinal and transverse displacement, and further improve the seismic performance of the bridge. The parameter sensitivity analysis of the combined seismic system shows that the optimal parameter range is : the friction coefficient is 0.04, the radius of curvature is between 3200 mm and 4200 mm, the damping coefficient is 6000, and the damping index is between 0.2 and 0.4.Under the optimal seismic system, the structural displacement and internal force are significantly reduced, and the maximum seismic reduction rates are 75.3 % and 82.3 %, respectively, indicating that the system greatly enhances the ability of the arch bridge to resist dangerous earthquakes, which will undoubtedly provide a case for the seismic isolation design of similar bridges at the seismic design level.

Key words： high intensity long-span half-through steel box tied arch bridge finite element seismic response seismic isolation technology friction pendulum bearing viscous damper
