And on the basis of the optimization theory, the optimal design model of the seismic isolation high-speed railway simply-supported girder bridge was established. Considering the longitudinal displacement of the beam and the pier shear of the pier as the constraint conditions, and the maximum of the bending moments at the bottom of piers as the objective function, the optimization method of the SQP was used to realize the performance parameters optimal design of the new seismic isolation system under seven earthquake waves. The results show that the new seismic isolation system have the effect of reduction control the longitudinal displacement of the beam, the pier shear force was reduced drastically. Through calculation analysis, the influence rules of performance parameters of the new seismic isolation system on bridge seismic responses are given.
