However, the aerodynamic effect in tunnels and underground stations usually affects the operation of trains and passenger comfort. Setting up shield doors is an effective way to reduce this impact. This paper aims to study the aerodynamic effect of shield doors in high-speed railway tunnels and underground stations, and provide theoretical basis for its design.Firstly, this paper introduces the aerodynamic problems of high-speed railway tunnels and underground stations and their influencing factors. Then, the influence of shield doors on air flow is analyzed, the influence of different shield door designs on aerodynamic effect is explored, and numerical simulation is carried out. Finally, combined with experimental data, the aerodynamic effect and applicability of different shield doors are evaluated, and corresponding design suggestions are proposed.Keywords: high-speed railway; tunnel; underground station; shield door; aerodynamic effect; numerical simulation.
