High-speed rail bridge combined seismic mitigation and isolation system design method considering train driving safety
The invention provides a high-speed rail bridge combined seismic mitigation and isolation system design method considering train driving safety, which comprises single-pin performance controllable seismic isolation support parameter design and multi-directional shear damper parameter design, and the single-pin performance controllable seismic isolation support parameter design comprises a support structure design method and a support mechanical model establishment method. And substituting the parameters of the multidirectional shear damper and the parameters of the single-pin performance controllable shock insulation support into a finite element model of the high-speed railway bridge, and analyzing whether the bridge pier top and pier bottom responses along the bridge direction and the track dislocation, the track turning angle and the track acceleration in the transverse bridge direction accord with a management and control target or not under different earthquake working conditions. By means of the combined design that the performance-controllable shock insulation support and the multi-direction shearing type damper are fused, the high-speed rail bridge can meet the large-rigidity requirement of normal operation of a train; and various performance requirements such as the safety of a train running at a high speed when an earthquake occurs and the structural safety of a high-speed rail bridge in the earthquake occurring process can be met.
