To look into the wind deflection responses of the sealing networks under the coupled high-speed train slipstream and wind loads

an analysis model for coupled high-speed train slipstream was established

and the wind-speed profile of the coupled slipstream was studied. Moreover

a dynamic response numerical model of the sealing networks was established

and the wind deflection response of the sealing networks under the coupled loads was analyzed. The results indicate that the high-speed train amplifies wind speed

and there is evident ’front-tail’ impact effect of coupled wind loads; under the coupled high-speed train slipstream

the vertical wind deflection response of the sealing networks are significant

and it can be diminished by increasing the pretensions in the carrier cables of the sealing networks effectively. For the common span length of the sealing networks

the pretensions in the carrier cables should not be less than 80 kN.
